Dark printing on the pages with the text


you will probably need a maintenance kit. After a while the toner roller and fuzer rollers wear down and allow more toner to be put on to the paper than is needed.

When printing on my Canon Pixma MP500, there is a dark black line down the middle of the page. As the pages print, it gets lighter and lighter, but is very dark on the first one. Any thoughts?


Ink tends to overflow at the bottom guide rollers and the roller gets coverd in ink and causes the black line!The best will be to take it to a dealer and have it cleaned!Good Luck!

Dell 1815dn laser printer prints completely black pages


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.

How to ink Casio FR 1211 Printing Calculator


I have a Casio FR-1211 Printing Calculator and I have the same problem. I removed the roller and tried inking the roller with "Sanford's Roll-On Stamp Pad Inker". It works beautifully ! I don't know how long it will last, but for now the print is dark and clear.

Ink blots deposit onto feed rollers which in turn transfers to all new prints


Most likely you have a leaking print cartridge (toner cartridge). Does it have the same problem if you use the Manual Bypass tray?

It could also be a worn fuser sleeve that is causing the print defect...the fuser would need replaced in that case.

Leaking black ink on printed pages


Hi, please attempt to run a numerous blank paper through the printer. This will dry or clean any ink found on the rollers.
Continue to run blank pages through the printer until no more ink is found on the paper, then attempt printing. If ink stains or streaks are still present, the printer may need service.
