Is the carriage rail clean, and lightly lubricated?

Cheat the door switch and observe the carriage moving at boot up.

(Keep your fingers out of the way!)

See if you can spot where it sticks.
Sometimes the printhead capping unit / service station seizes up, and the carriage cannot leave / return to the home position.

This model was not one of their best.... Good luck

did you perform a scan axis calibration after changing all these parts? If not then you should do that before doing anything else.

Error code 02.01.10

02.1:10 error indicates that the encoder is not working.
Try the following:
Switch power off and unplug the power cord. Reconnect and turn the power back on.
Check that the trailing cable is not damaged (wide cable that goes from the main PCA to the Carriage PCA)
Replace parts in this order: Trailing Cable, Carriage PCA, Main PCA.

Clarify: #Error appearing immediately with sudden ****? or while carriage parking in serve station area?# remove & take out service station, place it out side(to avoid capping/wiping by cleaners)..check
# check carriage bushing warn out condition( too much play of carriage causes this error)
# trailing cable flexibility good? or its obstructing the carriage path?
# take out cutter assembly from rail.. check..
# Check carriage belt tension, adjust if required.
# Check carriage belt properly installed? re-install again
Best of luck....

I have a hp 6100 series printer. I can not print. I get a message. Open door. Clear carriage jam and then press Enter. I do not see any jams.

Hi sir!
Could you inspect your printer for me and see if there is a long clear plastic that fell inside the rollers. This is called the Encoder Strip. This plastic strip is very important inside the printer. The carriage determines its position from the tiny lines on this encoder strip.

This plastic should be in its proper place, goes through the slot in the carriage, the other end of this is attached on a spring hook on the left and a stationary hook on the right. Hook It Back!! That will fix it.

Sometimes, these Clear Carriage Jam issues is brought about by hardware problem. And the best DiY solution for this is to reset the printer. Follow these steps before performing the reset procedure.

I hope this will work for you if my first solution did not work.
1. Unplug the power cable from the back of the printer (The other end of the plug should be directly connected to wall outlet)
2. Keep on tapping the Power button on the printer for 30 seconds, then plug in back the power cable at the back of the printer.
3. (Make sure no jam in the carriage) Open the carriage door and take out the cartridges, clean the cartridges with a dry cloth.
4. Make sure the power is turned on and gently move the carriage (Catridge holder) and check if anything is jamming it.

To reset the printer
1. Unplug the power cable from the back of the computer
2. Press and hold down the (#) and the (6) button at the same time, then plug in back the power cable
3. Release the (#) and (6) button (the printer may shut down) on the screen it will display SEMI NVM reset
(If none of them happens try it once more)

Another reset
1. Unplug the power cable from the back of the computer
2. Press and hold down the (#) and the (9) button at the same time, then plug in back the power cable
3. Release the (#) and (9) button (the printer may shut down) on the screen it will display SEMI NVM reset

If the problems still persist, You can call HP to return the printer and get an upgrade at low price for replacing the damage printer. hp no.: 1-800-474-6836

Good luck!

Carriage jam open door carriage jam and then press OK to continue

You would be absolutely amazed how small a piece of debris can cause that fault. Use a flashlight and look carefully for any piece of debris and remove it.

Get some "canned air" from any computer or office supply store and blow out the interior of the printer thoroughly.

HP 6110 Printer jams after 1 sheet


Thanks for contacting

Please try the bellow mentioned troubleshooting steps to help elliminate the paper jam and noise issue for your printer:

Things that cause a carriage jam error:

Dirty encoder strip.

Damaged encoder strip.

Encoder strip spring mount out of position so strip is slack.

Encoder strip not threaded through the emitter/detector that reads the lines on the strip. (just fixed a 5550 with this problem)

Emitter/detector that reads the lines on the strip is bad, this is part of the carriage PCA, (board).

Carriage stuck on side because service station is not releasing it.

Carriage stuck due to being tilted at wrong angle, if it's stuck a few inches from the right it needs to move farther to the right to be released, stuck a few inches from the left end move it farther to the left. (instructions probably on HP web site, they are there for the DeskJet 5550)

Carriage binding on rail due to ink build-up or lack of lubrication, (be careful what you use to lube).

Bad carriage motor.

Bad carriage drive belt.

Some machines have a timing disc on the service station motor and may indicate a carriage jam if the service station motor does not turn.

The cause could also be a loose cable connection on a small circuitboard inside the printer (The one that controlled the paper jam sensors) I fixed it by saudering the leads to the board until I had a good connection again.

Thank You and best of luck,.

Encoder strip for HP 2175 xi

Here's the solution for fixing a carriage jam on your PSC 2315xi printer. But, you said the encoder strip came off. I always understood that if the encoder strip came off, the printer was dead. I've never tried to take the encoder strip off and put it back on again to see what happens. The encoder strip is what tells the carriage where it is. Without the encoder strip, the carriage doesn't know where to go.

Make sure to check all the way to the right and left inside. I ussually find paper loose in either of those ends. Then check your encoder strip which is the plastic strip that the carriage slides on. This may be dirty causing this issue. Use a soft paper towel and alcohol. Windex is okay to but may leave streaks on it and give same issue.
