How to put in a broken printer carriage. Encoder. Encoder line Printer type encoder How to know contacts

Good day friends!

Are you using an inkjet printer? I don’t know about you, but smart cars suit me! But be it a mind, human chi machine, you will need organs to feel, how to give information for processing.

"Organi pochuttiv" inkjet printer - tse yogo sensors. Let's take a look inside the printer today and find out if the sensors are there.

For the cob, it is significant that the ink jet printer is an electromechanical system that can take revenge on the broken parts and electronic stuffing.

Inkjet printer as an electromechanical system

Printer electronics microprocessor system.

Tsya system is similar to tієї, as it is installed in the system block of the computer, only a little less tightness.

Vaughn may at her warehouse a small amount of input and output.

Come out with vikonavchim mechanisms (electric motors), like crashing a carriage with a head and serving paper.

More stench is “marked” by light indicators, which show different modes of operation of the printer and nozzles of a different head, for the help of which ink is applied to paper.

• other head,
• service station for cleaning,
• dzherelo secondary electricity, which provides energy to the mechanisms and electronics.

Other heads can be a dekilka, stench can be taken from the ink tanks and restored to normal. The service station can be called a dvigun.

Signals are sent to the inputs of the system from the buttons on the front panel of the sensors, which are the “eye” and “woof” of the inkjet printer. Axis about the rest and talk about a few reports.

Mechanical sensors

Smartly, the sensors can be divided into two large groups. mechanical and optical.

Mechanical sensors may have a micro button in their warehouse and (neobov'yazkovo) which is important or traction (lower).

When a button is pressed on the microprocessor system of the printer, a signal is sent, and the printer reacts to it in an appropriate manner.

As a rule, the printer cover open/close sensor is mechanical.

The krishka can be on its own turn, the traction is important, like with its own pushing onslaught (or pulling it) it will open the micro button.

The printer responds by moving the carriage with another head into the replace cartridge position. Sound during pauses in the robot, the head is in the extreme right position (at the parking position) above the gum cap (gasket), which changes the breathing of other nozzles.

Buttons of life, stretching the paper, selection of the robot mode and also mechanical sensors.

Some models of printers can be different both on paper in different formats and on CD-ROMs. Vibіr zdіysnyuєtsya for additional help, which is the connection with the sensor (mostly mechanical). Opiuyuchy sensor, control circuit "know", de won can be different.

Optical sensors

Optical sensors are the “eyes of the printer”.

The basis of such a sensor is optocoupler.

Optocoupler є photodiode and light diode, roztashovannymi on a close vіdstanі one vіd one.

Svіtlodiod viprominyuє see light (or infrachervone vipromіnyuvannya) at the bіk photodiode, photodiode tse vipromіnuvannya priymaє.

If the light flow from the light diode is consumed by the photodiode, at the output of the photodiode there is a signal, if there is no light flow, or if it is blocked - there is no signal.

In most vipads, a pair of light-diode-photodiode is protected by an opaque casing with narrow slits. This was done in order to ensure more clear information and to turn off third-party lights.

Why is it important to use the method of optocoupler in the infrared range which allows you to greatly change the infusion of daylight.

To control the visibility of the position of the paper in ink jet printers, the optical sensors themselves are usually installed. Krіm optocoupler, such a sensor can take away a light curtain, which rotates, so that the light flow in the optocoupler is interrupted.

If you put paper paper into the feed path (without being in the middle in front of the other zone), then lift the shutter a little. Vaughn cuts off the flow of light, and the printer knows that the arcade of paper is pidijshov to the zone of the friend.

Encoder sensors

There are two more optical sensors, which are the same for all models of inkjet printers, which are the simplest ones.

Go about encoder sensors.

One of them is a narrow, transparent line with black, opaque strokes often applied to it.

This line is firmly fastened in parallel and more directly, like a carriage with a different head is collapsing.

The middle of the carriage is an optocoupler and, if the carriage moves, the optocoupler collapses in the encoder line, intertwining opaque strokes and the light space between them.

Potik viprominyuvannya in the light of the optocoupler is periodically interrupted, so the output signal of the photodiode may form the form of pulses.

Thus, in respect of the impulses of the encoder optocoupler, the microprocessor system check the position of the carriage with a different head.

Following the same principle, the encoder sensor is used, which is the legal format of the paper, which is victorious.

Sound the vins of the transfers at the left part of the printer, nearby the engine that controls the paper feed.

Vіn vykonanyy vyglyadі transparent disk z applied to the edge of the radial impenetrable strokes.

In respect of these strokes, the electronic circuit “knows” that part of the arkush is already overhanded (otherwise it has been scrolled for an hour of stretching the paper).

Other optical sensors

Є і sensors (optical sensors) of color calibration.

Differently see the paper can change the texture (matt, glossy, etc.) and different whiteness steps.

Color indicators of ink on original cartridges can be changed from batch to batch.

To bring the colors to the level of a “sleepy banner”, the colors of the calibration are victorious.

When calibrating the color, the printer will perform a different test when looking at the color shapes. Let the carriage with the sensor pass over the overwrought area, and light will vibrate the light at the back of the overwrought image.

A photodiode, which is also found in the caret, captures the light, the spectrum of which is analyzed by the control scheme. This information is secured by a distant robot.

For another type of paper, re-calibration is required.

Come on, how to get out! For the help of simple gizmos - buttons, shutters, important, optocouplers, plastic pieces with strokes - it is safe to complete the high intelligence of an inkjet printer!

For help, the same detectors are waiting for the printer. On the right, when changing heads (or cartridges), the nozzles may change a little. With this, the accuracy of pouring colors will change. In addition, the mechanical parts of the printer wear out and show play. All this causes a deterioration in the clarity of the image.

The printer has several different test shapes (squares, rectangles, strokes) with fixed positions. Let the carriage re-pass through them and read the beat signal. Otriman information is insured by a distant robot.

I should say that some of the lines on the encoder lines and disks can wear ink. Normal operation of the printer may be damaged.

If the encoder lines are clogged up, clean the disks with clean (preferably boiled or distilled) water.

Likewise, pigment or solvent inks are vicorated - they should be special. Kindly read the article about the inkjet printer on this site.

With you buv Viktor Geronda.

Until the singing hour, I didn’t think about any kind of broken carriage on my inkjet printers. Keep calm until the problem literally creeps up behind you. Chergov's photograph came out of the printer in raptom, calamity, not sharp. Having reviewed the photo on the monitor, the clarity is clear. I understood what was said about the printer. Checking the nozzle test - everything is miraculous. It looks like the calibration of the other head was broken. Let's try to calibrate. I go to the Start menu - Add printers - I choose my printer - Set up a friend - Services - Calibrate the other head. And here I’m running, it’s about an hour of calibration, the printer began to create a brand name - the carriage began to literally fight against the side wall of the printer. "Head" has spent landmarks. It means that it has collapsed, which gives orientation. Shukati didn’t have a chance for a long time - the problem arose at the muddled encoder. Encoder(eng. Encoder) - a thin line of transparency that goes along the entire length of the printer behind the carriage.

There is a sensor on the rear wall of the carriage, which is positioned and reads the information from the encoder to the printer. The encoder has its own line with marks, the printer has a great accuracy with other images. It's not surprising that when the line got lost, the printer's head, as it is called, "died".

If your printer is installed, then the encoder will be polluted often. Some models of printers (zokrema, Canon) start to look different, seeing the pardon of a carriage failure. But now you yourself can solve this problem.

I cleaned the encoder with a clean ganchirochka soaked in water. You can vicoristovuvati alcohol rozchin. Gently wipe the encoder from both sides along the entire length. For convenience, put the printer in cartridge replacement mode and, if the carriage is in the middle, pull out the life cord. Now you can manually move the carriage to the left and to the right and clear the encoder all the way.

Under the hour of purification, do not overdo it, be careful. If you stretch yoga, or screw it up, you'll get shukati a new encoder.

The cleaning took less than five minutes from me, and the next time the photograph was taken, it showed that the printer is now in order.

I have done the same procedure with a prophylactic method on Epson T27, which I use for . Youmu can't be bothered with cleanliness either.

By the way, for a similar repair at the service center, you would have had to pay a chimal sum. But now you yourself know how install broken carriages on your printer.

The encoder is an attachment that converts linear or kutove movement into a sequence of signals, which allows you to set the magnitude of the movement.

The encoder line in the printer is the navigation system. Without a line, the printer will not be able to understand if someone has a different carriage at the moment. And without which it is impossible to understand, at some moment it is necessary to start drukovat and de finish. The line of the raster of the vikonan is most often on the sheets by the photolithographic method. With a thin transparent polymer plіvochkoy, with black opaque females applied to it. If you marvel at the line of the raster under the big fold, you can clearly cheer on the wife.

Stitch the raster sensor behind the encoder line. You should be on the carriage and send a signal, at some point in the next hour, start another, and at some time, finish it. It is unacceptable to fix the printer by sticking the encoder sensor by the ecoder line. In this way, these lines are read incorrectly, it is possible to pardon the position and the diversity of the incriminated picture. Also, there is a trace of the uniqueness of the retailers or the ink on the inner part of the encoder sensor. You can bring the lenses to fogging and bring the raster sensor into harmony. The encoder sensor is foldable with an infrared imager on one side, and a photodetector on the other side. Principle dії sensor raster attacks. Passing over the dark and transparent females on the line of the raster, the sensor sends a signal to the printer's card, which determines the position of the carriage according to the post position. Parts of the fall, if through a filthy stretched line of the raster, there is a splitting of the image or a sound through the skin passage. If you suspect those who have worn the encoder line, then you can try to turn the encoder line back to front or uphill with your feet. In 50% of cases, this kind of help helps solve the problem, I tied it with a line to the encoder.

To clean the line, the printer is guilty of blemishing.
On older models of printers, the encoder line is not protected in any way and can be seen without any particular problems, on newer models it is covered with a metal cover. If it is necessary to clean it, it is necessary to carefully, and then pull the casing up and on yourself. Todі vіn vyskochit іz pasіv. Don't mess up the line.
After cleaning, the line must be inserted at the special groove. The stitch can be perpendicular to the rail. If not, then it didn’t mean she was in the groove. Snap the casing back at a few places. After clapping, fuck yoga on the rack. To walk mentally and freely means to flicker. Let's run the carriage with our hands along the rail for a chip.

It is necessary to clean the stitches, vicorist soft material, which does not damage the encoder mill. For example, a lint-free servo. When cleaning, do not press too hard on the line, the shards can be used to erase the marks on the surface of the line, and the stench is important for the correct re-switching of the carriage. You can clean the sensor gently with cotton swabs.

Early in the life of skin self-consciousness, one blames the need for buying something such that it does not sound like a recession. Axis and I'm alive so calmly and about the encoder I don't think about it.

I want to know the details of robots with maw encoders. As if in one and virobiv victorious encoder from the printer.

In my history, everything went smoothly. Povozayuchi svoіynimi forums squandered on the competition. The site (I won’t name it, because Rozmov is not talking about it) having probably promoted the results and plus one of the members of the forum, having promoted their Russian selection of products. І rozіgrovavsya set of іz 3 kits for self-selection of servo controllers. I registered on this forum by submitting an application (at once from 3 or 4 more than participants) and ... winning.

So I became a volunteer of 3 sets for choosing servo controllers. Dali me needed enkoderi. Let me explain for readers who are not so deeply bored in electronic components, what is a servo controller, an encoder and everything is worth it.

There are two main ways to handle accurate movements in CNC machines (numerical program control). I'll try to explain in my most accessible way, without folded schemes and terms.
The first way to move the blood. A small dvigun can be folded - a sprat of a coil, which attracts the core at the given positions.

The number of positions, in which the core can be fixed, are called crochets, intermediate positions (regulated by different intermediate voltages and magnetic fields, respectively) are called microcrocs. The driver behind the throttle motor is the control board, as a rule, with micro-jumps, the valves regulate the stream that flows through the motor. Signals are sent to the input of the driver: Enable (enable the robot to turn the motor), DIR (directly wrapping), STEP (small arms, it is necessary to turn the shaft on the motor). І driver translate commands into engine revolutions. Even more simple is that superficial construction. Minus - the speed of the wrapping of the engine is circumscribed through its constructive, and if the engine is missed for these other reasons, then the program that controls it does not know about it. Zvіdsi i sfera zastosuvannya - low i srednоshvidkіsnі dvigunі in zadіy oblastі navantagen. For example, 3D printer or hobinnі typesetting.

Another way to move around is a servomotor. The motor itself can be like that, a permanent or a changeable strum, there is no difference. One umova, yogo shaft is guilty of mother encoder. Encoder - tse attachment to the position of the shaft at a given moment. We will talk about the encoder in a little more detail. The servo controller is the main principle of operation, at the discretion of the driver of the crank engine. The servo controller accepts the signals Enable, STEP, DIR at the input and supplies voltage to the motor. The engine starts turning in the right direction, the encoder turns data about the position of the engine shaft. As the necessary station is reachable, the shaft of the engine is fixed at the new one. Well, it’s well-forgotten, because є speeding up that galvanization of the engine, control of the strum and tension, proportional-integral-differential (PID) regulator at the circuit of the swivel link, but we didn’t get too far into the theory.

These are the pluses of servomotors: be it a swidkiness wrapping, the ability to skip crocks, noiselessness (the crockery dvigun is noticeably loud in robots through its construct). Ale vartіst servo controllers are things and, of course, drivers of crank engines. Therefore, the main niche of servo controllers is professional zastosuvannya.

For my project, I chose Dynamo Sliven engines. These dviguns were widely celebrated for the Radian hours in the EOM and their number was unrealistically large. Well, it’s practical to be a hobilnik or maybe such a dvigun chi sticking with him. At flea markets, resell them. Tse dviguny postіyny strumu with a fantastic resource and stіykіstyu to be-any znuschan.

As a servo controller, I won the board. Vaughn is a development of an open source servo controller, under the stable brand "Chen's servo controller" - in the name of China, the year of 2004, so I don’t have mercy, scho zaproponuvav tsyu scheme.

Now it’s practical to move on to the essence of looking around – to encoders. Selecting an encoder depends on the characteristics and price. Yakі buy types of enkoderіv. Mainly optical and magnetic. Magnetic - if magnets are fixed on the edges of the disk, and there is a Hall sensor next to them.

Decision on the road, promise, maє pіdvishchenu nadіinіst. The price is not hobiyna at any time.

Optical encoders. The broadest solution. E in the skin mouse. Earlier, they gave the bag for wrapping that kolіshchatka. Now the bag is no longer there, and the axis of the column is gone. The principle of work is simple - cutting through the light beam is impenetrable by the body that can pass through.

Optical encoders are of 2 types: incremental and absolute. Incrementally divided into 2 subtypes. The simplest incremental ones are like they are depicted on a little thing. The stench is used to change the flow of light and on their basis it is possible to induce, for example, a tachometer. The disadvantage of this encoder lies in the fact that behind the help of a new one it is impossible to directly name a disk wrapper. Incremental 2-channel wrapping of the disk wrapper.

For this purpose, not one photodiode is used, but a sprat, ring 4. They form 2 independent data transmission channels, and by synchronizing the signals from these channels, you can unequivocally generate visnovok about the direct wrapping of the disk.

What are the gaps in this incremental encoder? Marriage is one, but for a number of zastosuvan vin critical. When initializing the encoder, we do not know what position the drive is in. Tobto. we can only directly recognize that swedishness of the wrapping of the disc.

For otrimannya novnoї іnformatsiї, and for itself - on the basis of the position of the disk, directly that swidkіstvo wrapping is an absolute encoder.

Absolute encoder victorious disc with folding position coding system. The largest expansion of the Gray code is a double coding from the protection of pardons.

I've loaded my choice on an incommental encoder with a direct wrapper control, that's it. from two quadrature channels for displaying information. Allowed 100 lines per disk for less than 1 point. Therefore, on Aliexpress, I know enkodery for a reasonable price and with the required less characteristics.

Axis photo of 3 encoders that I received. Dishli stink tizhniv for 3.

Encoders have 4 visnovkas, Chervoniy - zhivlennya 5V, Chorniy - land, Kolyorov - channels A and B.
I screwed the bushing onto the motor shaft under the fastening of the disk, screwing in the shear from the grooves.

On a 3D printer, having installed a maidanchik for fixing the encoder sensor

Zіbrav usі together

Having connected the servo controller, and ... then I’m happy to look around, but no. Nothing worked. Navit close did not earn anything.

Having connected the oscilloscope and understand that there are no daily quadrature signals at the output, there is only noise, inducing and unreasonable whistles. I'm sorry for everything in the world. І on the ability to position, and on the illumination, and on the electromagnetic guidance. For years, carefully moving the sensor at different positions, mimicking the light and making it sound all the same in the dark. "The crocodile is not caught, not the growth of the coconut." I realized that after trying all 3 encoders. Scratch yourself. And here I was struck by the sensor at the microscope.

Those that I babbled cheered me. All 4 sensors were in a row along the radius of the disk, tobto. lit up through the openings of the disc at the same time. I understood, nothing worked. The fault sensors stand perpendicular to the radius of the disk and light up sequentially with different fronts through the disk. I couldn't believe it, it's so simple and so stupid. The Chinese put the sensor with a 90 degree turn. I asked on the forum from the same way I bought the same encoders like a new sensor. And in the new one everything was wrong and did not work.

Pochuhavshi in the potilitsi I vyrishiv try to fix it on the right. The encoder was easy to crack, with the help of a hair dryer it melted the hot melt adhesive and removed the filling.

Bring the sensor up to the disk so that the sensors are across the marks. Obviously, the sensor did not get up correctly, but on the oscilloscope, the signal appeared as an understanding signal.

The photo shows that the sensors have become perpendicular to the radius of the disk.

Zіbrav, connecting to the servo controller and ... Bingo, everything worked out! The engine has become in the regime of the utrimanny position. Tobto. when you try to turn the motor shaft, the motor rests and if you still turn it, then it turns at the outer position.

Yak resume. The encoder is not available out of the box. I don't recommend before buying. Ale has its own price category, yakbi vin buv we can do it, the price garne is a budget solution. Otherwise, if the reworking of the viroba is not lakay, you can take it and remake it.

The seller has a bunch of positive reviews for such an encoder. Abo tse everything is a linden, abo, scho nayimovіrnіshe, shlyub pіshov masovo zovsіm recently.

Having written to the seller, I still sent me a ton of technical descriptions and try to try it, and try, I didn’t get it. I will press on a new one. Let me turn some of the pennies. I've been dying for an hour through my factory slovenliness.

All the best and satisfaction in your hobbies!
