2420 printer printing very squiggly as if you are looking at a reflection in water that has currents in the water, this is not a toner issue

Your printer may be out of toner, or the drum is not transferring toner to the paper correctly. Try replacing the toner and/or drum in your LaserJet to see if the issue is resolved.

replace toner cartridge u may have a worn drum in the toner cartridge or low toner

1) try doing a full clean from within the menu on the printer, or within the computer software
2) You need to perform a half test. Put a sheet of paper on the manual feeder and do a config page from the information menu on the printer. When the back edge of the paper enters the printer, quickly open the toner door to stop the printing. Now remove the toner cartridge and look at the image below. If the defect is present, then the toner cartridge is the problem 99% of the time. There is a slight possibility that during the conditioning stage of the print process the drum of the toner is not being fully discharged so when the next stage takes places part of the previous image gets put on the toner cartridge again. Very rare. If the defect is not present then the fuser has an issue.

This means that the printer is unable to read or find the toner cartridge memory chip. In some cases turning the printer off, removing the toner cartridge, reinstalling the cartridge and turning the printer back on sometimes correct this issue. But if that does not work, you will have to replace the toner cartridge.

maybe a driver issue .. look for the driver of ur printer..
uninstall it.. and re-install it back on ur computer.. if this wont work.. hardware on the printer is having a problem

Hi,

Please print a configuration page from the control panel of the printer
- Menu > Information menu > print configuration.
- Check for paper handling details.
Following setting should reflect.
Tray 1: Any size / Any Type
Tray 2: A4 size / Plain Type

If the above settings are not reflecting in the configuration page, please change accordingly by browsing on the control panel of the printer to:
Paper Handling Menu >
Tray 1 Size: Any
Tray 1 Type: Any
Tray 2 Size: A4
Tray 2 Type: Plain

Let me know if that helps to solve the issue.

Regards,
Nikhil.

remanufactured / compatible toner? sounds like defects to me. try OEM, or another supplier

Check (and remove) the "economode"in "Printer Preferences" (right click on Printer applet) normally in "Paper /quality" Tab

take out toner cartridge and wipe the compartment where toner cartridge fits with dry a microfiber towel if this doesnt work Replace toner cartridge with a new one somtimes when toner is low it will make lines and dump excess toner

Hi within the driver printing preferences you are able to change the graphic mode if you do this it may help. Without seeing what you are trying to print cannot give a accurate answer so try this and get back to me if this doesn't work

Hope this helps you and please rate me
Thanks J
