When I scan a page I am getting a completely black page as a result. Likely culprit?

Do you get the same result/image when scanning to your computer? Remove the cartridges from your computer. Then close the printer cover.Unplug the power adapter from the printer.


Wait at least 10 seconds before replugging the adapter into the printer. This will give enough time for the printer to reset. When the printer turns on, reinsert the cartridges. Try to make a copy or scan again. If you're still getting the same result, I would strongly suggest you to contact Lexmark technical support for additional assistance.

Get a damp soft cloth and clean the scanner glass. If that doesn't resolve the issue there is a chance the scanning unit itself is damaged.
Let me know.

1. Charge – Print Quality (PQ) -- The charge roller evenly distributes a negative charge on the photoconductor (PC) drum. This evenly distributed charge acts as the film that is discharged (exposed) by the laser to create the latent image.
a. Print Quality effected: Faint, Entire Black background, Grey Fog/Haze
b. Parts Involved:
i. Drum -- A drum cartridge is coated with a photoconductive material that allows electricity to pass when exposed to light. As an example of why this can be the failure, if you leave a drum out in light long enough, you will get dark backgrounds or just black pages. However, drums do wear out over time too; specifically the photo material the drum is coated with. As this degrades, more of the positive electricity on the inside of the drum gets through and grabs toner, as if the laser wrote to every square inch of it. A damaged or defective PC drum can cause black streaks/lines, voids, speckles and various other print quality problems.
ii. Charge Roller – Also known as the BCR or Bias Charge Roll. The charge roller pulls double duty. It energizes the outside of the drum with negative energy and as a result it cleans any previous latent images. If the charge roller were failing to energize either due to the HVPS or the charge roller itself, it wouldn’t clean any previous unused toner deposits from the last revolution would start to accumulate and appear on paper more and more causing haze. A missing charge roller causes completely black pages.

iii. HVPS – High Voltage Power Supply -- Responsible for charging components such as the inside of the drum, the charge roller, and transfer roller. If the HVPS does not give enough to the charge roller it can fail in erasing the drum, causing entirely Black pages to be printed.

You have a defective or disconnected SCANNER BLOCK

Try to disconnect the power cable from the back of the unit and reconnect it after few secs. The alingment will start itself. Complete the alingment once.

I called technical support for this issue previously with my brother mfc. It would only do this during color scanning. b&w scanning was just fine. The tech support put me through resetting the reference point of the scanner through a series of button pressing and closing and opening the paper feeder. I kept gettting the same lousy results. Then they determined that the scanner module needs replacing and I needed to take to the nearest service center.

There is a small strip of glass on the left side directly under the edge of the scanner, About a half an inch wide. It has something on it.
May be very hard to see, use a strong glass cleaner or some alcohol and a regular piece of paper to clean it with.

I assume you mean the pages are coming out dirty or gary versus white and black text.
change the drum/cartridge, if you get the same results it could be the hi-voltage power supply. most common is the drum.

The tech support at HP said its a hardware issue, especially if the following test results in a black page:

1) Open cover
2) Push scan button

if the bulb doesn't come on or the page is still black its a hardware issue.
