1. The tractor encoder signal is faulty.
a. Clean any toner or paper dust out of the encoder sensor.
b. Inspect the tractor encoder wheel for damage. Replace it if necessary.
c. The encoder sensor is faulty. Replace the tractor encoder board or the entire tractor
unit.
d. The fuser drive clutch is slipping; replace it.
e. Replace the Engine Controller Board.
f. Replace the encoder cable.

�� Tractor Encoder. The Tractor Encoder Board has two optical sensors that sense the
1/8 inch and 1/16 inch slots in the Encoder Wheels. These pulses are sent to the Engine
Controller Board and are used to monitor and control print location and paper movement.

Location
Remove the Tractor Encoder Cover by removing 1 Screw.
NOTE: Upon installation, the groove on the bottom of the Encoder Cover should
straddle the top of the left end of the Tractor Frame.
Left side of printer, just left of the tractor assy.

My printer shows "Hardware Error


  1. Remove the power cord from the unit.

  1. Gently move the top part of the printer belt to the right.
  2. Using your index finger, gently push encoder strip down and then back up to get it back into the slot located on the back of the ink cartridge carrier.

While working with the encoder strip, check it for dust or any unclean spots. If any detected, try to clean the strip by wiping it gently with clean cloth.
  1. Gently press the strip first to the rear and then forward to ensure that it is seated correctly.
  2. Manually move the ink cartridge carrier to the left, then to the right to check the positioning of the encoder strip.

How do I fix hardware error: 0502


Hi There, Please follow the below steps to get off this error :
Re-position the Encoder Strip on your Printer

To re-position the encoder strip, perform the following steps:

1. Remove the power cord from the unit.

2. Lift the lid of the unit, just below the scanner portion of the All-In-One, to expose the inside of the unit where the printer cartridges are located.

3. Gently slide the ink cartridge carrier to the middle of the printer.

4. Gently move the top part of the printer belt to the right.

5. Using an index finger, gently push encoder strip down and then back up to get it back into the slot located on the back of the ink cartridge carrier.

NOTE
NOTE: There is a small slot that the encoder strip fits into, which is going to be located on the back of the ink cartridge carrier.

6. Gently press the strip first to the rear and then forward to ensure that it is seated correctly.

7. Manually move the ink cartridge carrier to the left, then to the right to check the positioning of the encoder strip.

8. Once the encoder strip has been re-seated, close the lid to the unit.

9. Re-connect the power supply to the All-In-One.

10. Press the Power button. If the encoder strip was re-seated correctly, the Hardware Error: 502 code will not appear.

See attached pictures, one for an out or place encoder strip, the other for a well placed strip.

Other faults that can bring up this error is a carriage rail that needs cleaning and oiling (so you might want to do that while your inside the thing), and also obstructions to the paper ways. Try removing paper jams, and put the printer upside down to shake loose anything that might jam the mechanism.

Printronix L1524 is printing very faded labels. OPC Drum is brand new. Everything looks good, in my opinion. I believe it it is the wire below the OPC Drum and the label that is the culprit. any help?


This can be caused by a worn corona transfer wire. It can also be caused by the follow;
Developer starter toner is weak, change developer.
Laser Sight Glass is dirty, Clean, it is located under the top of the printer.
Transfer unit, bad, or poor grounding.

A THIN plastic strip about 1/4 X 16 INCHES LONG HAS BECOME SEPRATED FROM MY X4270 PLEASE ADVISE HOW TO FIX


Hi,

This clear plastic strip is responsible for telling the print head where it is horizontally. Pls note that it has black stripes almost like bar codes. Both ends of this encoder strip normally would have holes for hooking up to lock tabs on both ends. What is important is that this strip is embedded in a slot at the back of the print head that reads the bar codes/locations.

This page may shed additional insights.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

1. Ink cartridges lids are open which is not allowing cartridges to move freely.
2. Ink cartridges carriage will not move from its original position(left) when front cover is opened
3. Encoder strip is Dirty.
4. Encoder strip is Out of position.

Solution:
1. Open the front cover and check if ink cartridges lids are properly snapped in.

2. Turn the printer off and pull out the power cable from power socket, open the front cover and manually center the ink cartridges carriage.
Clean the metallic rod inside the printer using WD40 or Kleenex from Left corner to right corner properly.

3. Cleaning the encoder strip:
a. printer should be off and disconnected from power.
b. open the front cover.
c. Using a dry, lint free cloth, pinch the encoder strip on the right-hand side of the cartridge carriage and pull your fingers across it toward the right-hand side of the printer and you can move the cartridges carriage to clean the strip completely.
d. Note: The encoder strip is a narrow band of clear plastic and can be difficult to see without direct lighting running parallel to metallic rod.
e. Close the printer and try again to print.

4. Repositioning the Encoder strip.
a. Remove the power cord from the printer.
b. Open the front cover.
c. Gently slide the ink cartridge carrier to the middle of the printer.
d. Gently move the top part of the printer belt to the right.
e. Using an index finger, gently push encoder strip down and then back up, to get it back into the slot located on the back of the ink cartridge carrier.
f. Gently press the strip first to the rear, and then forward, to ensure that it is seated correctly.
g. Manually move the ink cartridge carrier to the left, then to the right, to check the positioning of the encoder strip.
h. Once the encoder strip has been re-seated, close the scanner lid.
i. Re-connect the power cord to the printer and try again to print.

Won't print in landscape mode


at the adobe print preview screen, does the preview agree with your desired print? if yes, then is "choose paper source by pdf page size" checked on? and is "Auto-rotate and center" checked on?
