This unit needs an imaging drum and to be calibrated. It should automatically calibrate after installing the new drum. You may have to "run off" a few dozen pages after the new drum is installed to remove any excess toner that remains.

Hi! I just changed my print cartridge (HP LaserJet- C7115X, ink 15x) and the printing quality is still low! It's as if it's still running out of ink, however the cartridge is brand new. Please help!


Did you remove the strip that the printers ship with? If the pull tab is still in then there is typically enough toner to print a few pages and then it fades out. Remove cartridge and check on left and right hand sides for a plastic loop usually orange. The instructions would have been in the box.

MY HP ''COLOR LASER JET 2600n'' HAS FUOLL INK CARTRIDGES BUT THE PRINTING IS REALLY DULL AND FADED LOOKING. CAN ANYONE HELP? TERRY M.


This is a common problem with this model of printer. The scanner optic degenration is due to dust buildup on mirrors and lenses. Since the most vulnerable mirror reflects its laser beam to the magenta toner cartridge, red tones are the first to show fading. Colours shift: purples turn blue and oranges turn yellow. The printer will need to be cleaned by a certified HP technician to resolve this issue as it means dismantling your printer to fix the problem.

Black toner replaced; now all black printing comes out faded grey


I have to ask this question of you, just to make sure this is not an issue. Are you using a factory new ink or toner cartridge?
Please consider the following:
If you are using a refilled or third party cartridges that may well be your problem. Most manufacturers build logic into their products to prevent the use of “Other Equipment Manufactured” cartridges as well as re-filled cartridges.
They do this to prevent problems from contaminated inks or toner causing problems with print quality or damaging the physical printhead or photo conductors.
If you are using factory new ink or toner cartridges, then please call the manufacturer’s Technical Support for assistance with the warranty on the cartridges

HP Laser Jet 4700n-Light printing on right side of paper. Removed all cartridges and toner, cleaned and recalibrated after start up. Still light printing on right side. Any suggestions??


Is the light printing the same for black and white vs color? Light printing on a side is not uncommon for these printers. It is usually caused by the laser optics getting dirty. But this usually shows up more in one color than the other. Such as something printed in yellow is fine while red is faded on one side. If the light on the right side printing is the same on all colors including black then I would suspect something with your transfer unit.
If you do notice that it us just on black or another color then it is definately time to get the laser optics cleaned.

Color laser printers. Costs for toner vs. initial costs for ptr


Have you thought about having your printer cartridges refilled? There are huge savings to be made in doing so and the quality can be just as good as the original cartridges (depending upon the refiller). Another option would be for you to purchase an older color laser printer such as the HP Color Laserjet 4500 or 4550. I use one myself and couldnt be happier with it. And as its an older printer, you can get the cartridges relatively cheap.

Faded print on one side of page


I have a SCX-4100 Samsung, replaced the tonger cartridge, it was working fine for a few hundred sheets of printing, but after that, the left side of the page was printed very light, faded.
If I run the "Clean Drum", it will print a litter better, but still faded.
What can I do to correct this problem?
Thank you
