How do I reset ms610 imaging unit?


When you get the error message "Replace imaging unit, 0 estimated pgs remain [84.3x]" This means the imaging unit has reached end of life and needs to be replaced. The device will not print, and this message will not be cleared, unless you replace it with part number 50F0Z00
(or 500z)
Vertical streaking. If the imaging unit is near end of life, or the device has had problems with non standard toner, vertical streaks may occur on the page. Replacing the imaging unit will resolve the problem.
Vertical streaks on page
Vertical band at top of page. This typically appears on printed images, but can also appear on text. The most likely cause is toner contamination on the charge roll, however if the band is still visible after printing 30-40 continuous pages this means the imaging unit needs to be replaced.
Vertical Banding on images
Seal failure on the imaging unit. Occasionally seal leaks have been seen from the Imaging Unit.
Toner will be seen on the main frame near the Imaging Unit sides.
If toner build up is excessive, it may even fall into the Tray below. Cleanup with a toner vacuum may be needed.
Replace the Imaging Unit to fix the problem.
Spots, scratches, marks on the page. If they are random, this indicates a problem with toner scatter.If they are repeating patterns, measure the distance between matching marks or spots. If the distance is one of 97mm, 47mm or 38mm, this indicates marks or dents on the imaging unit and it will need to be replaced.
You receive the message Replace defective imaging unit The imaging unit is defective and needs to be replaced. If you just installed it, it will be covered under warranty - contact Lexmark Australia on 1300 362 192
You receive the message Reinstall missing or unresponsive imaging unit and the below instructions don't resolve the problem. Try one or more of the following:
  • Check if the imaging unit is missing. If missing, install the imaging unit.For information on installing the imaging unit, see the "Replacing supplies" section of your device's User's Guide
  • If the imaging unit is installed, then remove the unresponsive imaging unit, and then reinstall it.
  • Note: If the message appears after reinstalling the supply, then the imaging unit is defective. Replace the imaging unit.
You receive the message Replace unsupported imaging unit The imaging unit you attempted to install was either non-genuine, or was from a different region. Buy a genuine Lexmark imaging unit from an authorised Lexmark supplier in your country/region.
You receive a 31.6x error One of the following errors is shown on the display:
31.60 Imaging unit smart chip error
31.61 Imaging unit I2C packet timeout
31.62 Imaging unit I2C packet has been sent but code timed-out on receiving the data (callback)
31.63 Imaging unit security error in the send challenge sequence
31.64 Imaging unit ROM signature error
31.65 Imaging unit stuck busy (status register and/or CRI Arbiter register report busy)
31.66 Toner failed to replenish into the imaging unit
In this case you need to ensure that the imaging unit is properly installed. If yes, check if the imaging unit is supported. Replace with a supported imaging unit if necessary.
If the problem remains, you will need to organise a Lexmark service call (Australia 1300 362 192)
You receive error message 32.11 Imaging unit smart chip compatibility error This could be caused by an unsupported imaging unit (non-genuine or incorrect region). Replace with correct imaging unit to clear this error. If your imaging unit is supported, you will need to organise a Lexmark service call (Australia 1300 362 192).
You receive error message 84 Imaging unit low If expected, replace the imaging unit. If unexpected, call Lexmark Support (Australia 1300 362 192)

How to fix vertical burns on screen


First of all, change the input device to some other which you know for sure works well. Look for loose contacts in jacks, sockets. Check whether you have kept any magnetic material on top or near the TV. If problem persists, it might need attention by a qualified service technician.

Scanner leaving black streaks


There are two possible fixes.

Download the latest firmware update by CLICKING HERE

The following is provided by courtesy of Lexmark:
Problem Vertical lines; Auto document feeder scan anomaly; ADF scanning problem; Scan issue; Scanner issue; Visible line; Streaks show on page; solid line down the page; Top to bottom line; Smudge runs down the page; Opaque line; Broken line; Bar all the way down the page Solution Overview

This article provides the self-diagnostic steps necessary to evaluate top-to-bottom streaks that appear when copying or scanning.

Important! This is seldom a scanner hardware failure.

The main reason for this anomaly is debris or marks on the scanner glass that is used for Auto document feeder (ADF) page scans.

Printed or Scanned Page Illustration

copyvertstreaks.jpg

Who should consider this article?

Any user of an MFP or All-In-One printer experiencing the following symptoms:

  • -Vertical lines only when using the Autodocument Feeder (ADF).
  • -Observed with any type of scan job (e-mail, ftp, solutions, fax).
  • -However, normal expected output when the page is scanned from the scanner flatbed.



ADF scan behavior

Think of it this way:

  • -The page is pulled from the ADF.
  • -The moving page slides across an ADF-designated portion of glass.
  • -The image sensor, which is located under the glass, reads and interprets the moving page's contents.
  • -Contamination on this ADF glass is seen by the image sensor for the entire length of the page.
  • -The image processor interprets the image sensor's repeated capture of this contamination as a vertical solid line.
  • -Any ADF scan function now exhibits a vertical line.

Suggested Diagnosis and Fix




Step Action 1 Locate the portion of the glass designated for ADF scans.
HINT: The glass location differs by model. This area is often separate from the scanner flatbed. Please reference User's Guide for more information if you are having a difficult time locating this designated area.
2 Perform a visual inspection for any of the following recurring culprits:

  • -Clear adhesive tape
  • -Glue
  • -Ink pen
  • -Paper
  • -Marker
  • -White out
  • -Staples
  • -Environmental dust or dirt
HINT: Ink marks can be especially hard to see and almost translucent at first sight. However, the image sensor (CCD) registers them as a mark. 3 Use a clean, soft, moistened cloth to thoroughly clean and remove any marks or debris. 4 Inspect the underbelly or underside of the ADF for any marks or debris. 5 Perform another scan to see if cleaning the glass alleviated the issue. 6 Repeat the procedure if a vertical line still appears.
Remember! Printing and scanning from the scanner flatbed work fine.
7 This time, place an intentional mark on a blank sheet of paper and take note of its location. Now place that sheet of paper in the ADF and make a copy.
8 Evaluate the distance of the vertical line to the your mark. 9 Inspect that area of the glass for further debris or marks and clean as necessary.

There is a mode in which you can lock up the mirror and shutter blades so that the sensor is exposed. Use a appropriate cleaning kit and avoid touching the sensor.

Black marks on pages


Can you stop the copy before the page gets to the fuser section? If you can and the doubling image is there you need to replace the drum cleaning blade and possible the drum as well. If the marks are there after the fuser section the problem is in the fuser. You will have to replace the Upper fixing roller. Good Luck... You may have a hard time finding the parts, this model is old and not a very popular copier..

If you see a very dim image or black screen or flicking image on the LCD screen it means you have a backlight problem.

Connect an external monitor to your laptop and power it up, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight.

Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.
