Question about Xerox WorkCentre M20i All-In-One Laser Printer

1 Answer

Light Copies and Print

The machine copies and prints significantly lighter than it should.
It scans fine.
I put in a new toner cartridge. I've also cleaned the mirrors and gone into the tech mode and re-calibrated the shadow setting. No change.
I need to get my machine up and working as soon as I can. Any suggestions would be appreciated.

    Thanks for the post. Window is cleaned. The three mirrors (two long rectangular ones, one larger one in front of the eye) are clean.


    A new power supply was put in a couple weeks ago.


    Is there someway to re-calibrate the darkness setting? That's the look and feeling I get that needs to be done. If I place the lighten/darken setting on the most dark, we're almost there.


    Your thoughts?


    Thanks.

Prints and Copies are lighter? You have a dirty laser.
You said Prints were fine in other posts.
Turn the machine off, remove the 2 screws holding in the left cover and pop it off. You can do one of two things. Either take a stubby screwdriver and feel around the laser for the 3 screws that hold it in and remove them. or once again remove the scanner and remove the laser from the top. There are 5 or 6 clips on the scanner , loosen them and pop the laser into half. Clean the window, all the mirrors and you will see a polygon mirror assembly on a motor. Clean each surface of the polygon mirror with a soft cloth and some cleaner, being very sure to get them spotless.
In your earlier posts you said prints were fine. That they are also light changes everything.
You could also have a bad power supply.

Our copier is copying in light shade. how to make it darker


To adjust the default lighter/darker setting

1. On the LaserJet 3015, press MENU/ENTER.

2. Use the < or the > button to select Copy setup, and then press MENU/ENTER.

3. Use the < or the > button to select Def. Light/Dark, and then press MENU/ENTER.

4. Use the < or the > button to adjust the setting. Move the slider to the left to make all of the

copies lighter than the original, or move the slider to the right to make all of the copies

darker than the original.
5. Press MENU/ENTER to save the selection.

Page 48 of the User Guide has instructions for adjusting the light/dark setting during a copy job.

Also see the Troubleshooting section of the User Guide for other possible reasons for light/faded copies.

If your copies continue to come out too light, you may need to clean the insert a new toner cartridge or change brands of toner. I tried several "generic" toner cartridges and refills, but my prints and copies were always faded or streaky. After going back to genuine HP cartridges, I haven't had any print quality problems.

Light print on side of paper. color black copies, print, internal


Ninty-five percent of all image issues like this are caused by the carona-drum-toner assembly. I have not worked on this model but the only way to diagnose the issue is to try a new drum / toner cartridge and see what impact it has. Then once you resolve the issue you can discuss the service life after the fact.

Dell 1600 - Print on copies is very, very light. We have put in a new toner and set the contrast to "Darker", but the copies still are light and hard to read.


Hello,
You can try a couple of things,
1. Verify that the pull strip was removed from the toner cartridge before it was supposed to be installed.
2. Shake the toner cartridge side to side to loosen the toner inside.
3. Clean the inside of the printer with a can of compressed air.

Good Luck!

The scanner copies everything with a dark shade. This happens when making copies and when using it as a computer scanner. It does print fine however. Everything was working fine until I took the toner out...


check the image density setting on the screen, put it at auto or mid way, if it is move it to the lighter side, Printing does not use the density setting. scanning and print do. let me know if this works

The copy of afficio 450 become lighter


You may want to consider putting developer into the unit. What is the copy count on the machine?

Light copies


You may have your machine set to print in "toner save" mode. Check your machine settings by printing a list. Also, some generic toner cartridges have too much polymer in the mix and will print light copies. If you change back to OEM toner, you may have to change the drum too, as the extra polymer stays in the drum unit and weakens the mix.

Panasonic DP-150PA Light Copies to no copies


Have you reseated the drum and toner?
It can be a drum cartridge problem. have you tried that?
You say copy or print, so I am asuming this is multifunction and you do both printing and copying.
1, Have you shook up the toner cartridge well.
After the drum and shaking the toner, I would suspect the transfer assembly, Off hand I cant remember of that machine has a transfer roller, or if there is a channel where there is a hair fine wire running through it.
The wire may have broken, or if its a roller making poor contact.
The laser is also possible.The transfer will be on the right had door assembly.
Take the cartridges out and see if there is anything laying loose in the machine,
what you are describing sounds more like a drum or transfer problem.
sounds very much like a defective transfer. And again, could easily be the drum.
Did you have a jam just before this occured? If you had a jam in particular in the right hand door, you broke the transfer wire.
Yeah, i am rambling huh?
