Check print path error after belt replacement (HP 1055)

Printer worked fine, but the belt wore out, so we replaced it. But now during start up it results in an awful noise and an error. Checked the belt, making sure it is installed properly with the teeth on the inside. Also checked the clutch system and to be sure lubricated it. It starts up and starts moving the carriage slowly to detect the sides of the printer. This works fine. It finds the right side, and the left side. Then it parks the carriage on the left side, after which it should start moving at regular speed. At that point the noise occurs and the error: The error is: "Check printhead path (Type 1)". Also, the noise is not coming from the clutch but from the engine that drives the belt (on the right side). I guess the engine runs and the ribs on the drive and the belt rubbing against each other are producing the noise... This is a *loud* noise, not some light scraping of hoses or the print head. So, either the print head is somehow "stuck" and cannot be pulled out of its position. But this is weird, because if I pull on the belt manually, the carriage comes out without much friction at all. Any suggestions are welcome

SOURCE: Does not print red, print heads do not return to left parked area

The printhead not moving to the left I think I can solve. Open the top cover, the yellow light on the paper feed button wil come on solid, press and HOLD this button until you hear the print head assembly make some noises (about 10 to 20 seconds) then release the button and then the printheads will move and park on the left so you can remove the printhesd(s)

SOURCE: weird noise from printer carriage

The loud clicking noise is probably the carriage trying to move and something is keeping it from doing so. Check to see there are no foriegn objects obstructing the carriage head from moving across the paper. If nothing is found, then likely a hardware error exists.
hope this helps!

SOURCE: We are receiving the error message Check Print

Upon power up, does the machine move the carriage assembly from one side to the other?

Generally, any message like that means the belt has a few teeth missing or is worn. The belt drives the carriage assembly to and fro. If the machine detects a slow down or stop, it will have you check the printhead path for obstructions. If there aren't any, then 9 times out of 10 it is a worn belt. Check for little pieces of black rubber under the belt and encoder strip.

I have also seen 2 other fixes: a dirty encoder strip (the plastic strip with little hash marks on it) and a faulty cutter. But most of the time it is the belt.

Hp designjet 1050c check printhead path (1) but the carriage barely moves?

Either the belt pulley is broken, or installed incorrectly, or the belt was installed backwards.

On my HP 1050C Designjet I am getting the error 'Check printhead path Type 2. Then it says to switch off.

Hello. The "Check Print Head Path" error is usually a worn out carriage belt on printers more than 5 years old. Open the top cover and examine the area under the belt and look for debris that looks like pencil erasure crumbs. Other possible problems could be the tube system catching on something as the carriage moves, the encoder strip being very dirty or extreme friction between the carriage bushings and the rails they move on. If the belt needs to be replaced, a replacement kit can be purchased at:
Hope this helps.

I have problem with my 5500 hp: check printhead path 2

The most common cause of the Check Print Head Path Error 2 is a worn out carriage belt. Open the top cover and locate the carriage belt. It is the long thin belt that extends the full length of the plotter. Use a light and look under the belt for debris that looks like pencil erasure crumbs. If the crumbs are there, the belt is disintegrating and needs to be replaced. See:

If there is no obvious obstruction in the print head path, the most likely problem is a worn carriage belt. Open the front lid and check for rubber crumbs under the carriage belt. If there are crumbs, the belt is disintegrating and needs to be replaced.

Check printhead path

Check for free carriage motion by unplugging the printer while the carriage is in the print area of the plotter. Open the top cover and move the carriage to check for free movement. If there are rubber crumbs under the belt, the belt is worn out and needs to be replaced. Manual can be downloaded from:

There's an error appears. It was error number 86

86.01 can be a couple of issues pertaining to the movement of the carriage assembly.
1. Too much friction in the Slider Rod. Lubricate the slider rod.
2. The Carriage is bumping into the Service Station. If the carriage
is stuck at the right hand side of the Printer and cannot be moved
out to the center of the Print Platen it is because the Service
Station cannot uncap the Printheads. In this case replace the
Service Station/Aerosol Fan Assembly.
3. Check the carriage belt for wear. Check the carriage path for debris. If the belt is worn, replace the belt. Also, clean the teeth on the carriage drive motor, the debris from the belt will accumulate on the teeth.

Switch power off check printhead (1)

Good morning. The CHECK PRINT HEAD PATH error is caused by the sensors on the print head carriage sending signals to the electronics that the carriage speed is incorrect. Generally, this is a mechanical problem caused by an obstruction, such as a paper jam or some other item in the paper path. However, the most common reason for the error is a worn out carriage belt. Look under the belt to see if there is debris resembling pencil erasure crumbs. If the crumbs are present, your belt is disintegrating and needs to be replaced. The parts can be purchased at:
