Field Awareness Review

The following slides contain issues that were seen during

product testing and may occur in the field. Please

familiarize yourself with each of these issues, as you will

be tested on the key concepts at the conclusion of the

lesson.

Samples and reference images are provided where

available.

Lexmark Confidential 3

• This new state occurs when the machine has determined that the

cartridge is out of useable toner.

• The machine will hard stop to prevent damaging the imaging unit

by running the device without any toner.

• The only way to clear this message and resume printing is to

replace the toner cartridge.

• Shaking the cartridge will NOT allow you to continue printing.

“Replace cartridge, 0 estimated pgs remain [84.3x]”

Lexmark Confidential 4

“Replace imaging unit, 0 estimated pgs remain [84.3x]”

• This new state occurs when the machine has determined that the

imaging unit has reached its rated page count capacity or its

cleaner capacity.

• The only way to clear this message and resume printing is to

replace the Imaging Unit.

Lexmark Confidential 5

31.21 Missing or Defective Imaging Unit Error

• Intermittent contact with the Imaging Unit and CTLS (Capacitive Toner

Level Sensor) can display this error.

• Removing and reinstalling the Imaging Unit will usually clear the error.

• If the problem persists, replace the Imaging Unit.

Note: Early production units will be more susceptible.

Lexmark Confidential 6

31.46 & 31.66 Reinstall Missing or Unresponsive Cartridge

• This is a cartridge issue where toner is not being replenished to the

Imaging Unit.

• This can be caused by the cartridge being empty, or not properly

installed, or a mechanical issue within the cartridge/bottle that is

keeping it from replenishing the Imaging Unit.

• Replace the cartridge to resolve the problem.

Lexmark Confidential 7

200.19, 242.xx Paper Jam when Feeding from Tray 2

• A combination of parts at the high and low end of the specification

range can result in tray 2 being misaligned with the printer reference

edge.

• Printing on A5, A6, statement and legal media will be more

susceptible to this issue.

• To fix the problem, ensure that the media being used is supported and

loaded properly:

– Set side restraints

– fan media

– flip media

• Best solution would be to load difficult media in a different tray.

Note: A change is in process to reduce/eliminate the problem.

Lexmark Confidential 8

200.05 Paper Jam

• This jam means the input sensor did not detect the trailing edge of the

media – usually because multiple sheets were picked.

• Most jams occur under the Imaging Unit, but can occur in the Fuser.

• Multiple sheets can be picked if the media is difficult to separate or the

separator rolls are worn or dirty.

• Ensure the media is supported and stored properly when not loaded

inside the printer trays.

• Media should be loaded properly:

– Fan the media

– Flip the media

– Adjust the tray insert side restraints before loading.

• If the issue persists, replace the separator roll assembly.

• See the pictures on the following page.

202.03 Paper Jam

• The leading edge of paper stops at the fuser without any damage.

Lexmark Confidential 11

202.03 Paper Jam – con’t

• On some early production units, it is possible that the gear on

the Fuser Drive Motor has worked its way loose.

• Inspect the fuser for any signs of damage and replace if needed.

BAD: Fuser Drive motor – GEAR OFF GOOD: Fuser Drive motor – GEAR ON

202.03 Paper Jam – con’t

• Check the Fuser Drive Gear by spinning it with one finger.

– If the gear spins quickly with little resistance:

• Replace the Fuser Drive Module.

– If the gear spins normally:

• Reseat the fuser

• Reseat the Fuser Drive Motor Connection on the Controller Board (J24).

Lexmark Confidential 13

111.21 Service Printhead Error

• The printer will post a 111.21 Printhead Error upon boot up or after

re-inserting the Toner Cartridge and Imaging Unit inside the printer.

• It could be due to the Printhead not getting the required power to

start due to faulty signal transmission caused by improper insertion

of the Toner Cartridge and Imaging Unit.

• The error means that the Printhead +5V power line was not ON

when the laser servo started. It is possible that the Printhead is not

defective.

• To fix the issue, reseat the Toner Cartridge and Imaging Unit.

• If issue persists, replace the Printhead assembly.

Lexmark Confidential 14

Display Issues on 2.4” Control Panels

• Possible issues:

– Flickering/flashing

– Illegible text

– White or blank screens

• Troubleshooting steps will be similar to the previous products.

• Check the connections.

• If it’s okay and the problem persists, replace the control panel.

Lexmark Confidential 15

Unable to Insert Cartridge

• This is due to the printer’s hold down feature dropping down.

• Manually lift the cartridge hold down while inserting the cartridge, until

service can replace part. See the pictures on the next page.

Repetitive Defects at Photoconductor Drum Interval

• The Imaging Unit is more sensitive to ESD which can result in

spots or horizontal lines.

• If the Photoconductor Drum is damaged, it will cause a repeating

defect at 96.8mm.

• Be sure to measure the defect interval accurately. The Fuser

repeating defect distance is 94.25mm - 95.2mm.

• Print the Print Defects Guide from the Help Menu Pages in the

Customer Menus.

• Since the dimensions are so close to the fuser, try swapping

Imaging Units as a possible action to see if the defect follows the

Imaging Unit or Fuser.

• Replace the Part causing the problem.

Lexmark Confidential 17

Compressed Print When Printing on 8.5” Media using A4 Fuser

• Most 220V printers are equipped with an A4 width fuser.

• When printing letter size paper on an A4 fuser, the image will be

slightly compressed to enforce 8mm margins on the left and right side

to ensure robust fusing. This is by design.

• As of firmware release P125/E215, there will be an option to crop the

image instead of compressing it. To make the change go to:

• Configuration Menu>A4 Fuser

• Select Compress (default) or Clip

• In addition, there will also be a letter width HV fuser available.

Lexmark Confidential 18

Horizontal Registration Variation within a Scan Job

• Scanned images will show some degree of horizontal registration

variation from page to page due to the mechanical deskew

mechanism.

• The registration error becomes worse with increased input skew.

• This issue is most apparent on Scan to File.

• To resolve or lessen the effect, make sure the originals are neatly

stacked and edge guides are tight.

False 283.05 Scanner Jam Error

• A false 283.05 scanner jam error is most likely due to dust build up on

a black Mylar strip at the 1st Scan Sensor.

• Use compressed air to gently blow debris off the Mylar or perform a

more thorough cleaning of the debris by removing the covers.

Squeaking, Grinding and/or Clicking Noises

• Squeaks (idle rolls, torque limiter), clicks (clutch, feed belt), and

intermittent grinding noises (transport drive 1st mesh, clutch) have

could be objectionable to a customer.

• To resolve the issue, do the following:

– Squeaking Noise – add dry lubricant to idle rolls

– Clicking Noise – clutch will click against its rotational stop every time it engages,

feed belt assembly will click against outer guide, both are normal

– Grinding Noise – deskew clutch can make a grinding noise if parts are out of spec

or it is damaged (replace clutch); grinding noise can also occur if the transport

drive bracket studs are damaged (replace transport drive)
