Printing white page

Remove all cartridges, make sure any tape has been removed from over the nozzle. Ensure that everything has been installed properly, then use your printer (prompts on device, or in printer>control panel) to print some test pages, realign heads, etc.

by dragging the black bar on the left with your mouse when
the cursor changes for resize

you might have printer set to print in black ink only check in settings if not re install printer driver then print test page if the windows logo comes out in colour and the text black everything is fine

try to check laser guide dust cover, if that not open when printing it goes white and no image to be print.

It will print with no ink it will just be patchy.
It is also best to not let them run out of ink as they dry up in the print nozzle a pain to get working again and uses a lot of ink as you need to do several head cleans.
You may need to turn it of at the power point then after 3 minutes turn it back on again.
Also reboot your computer it may have not have started properly.
This should reset it.

Head problem COPY many black text pages 50 or so run head clean if still white pages repeat up to 200 or so pages..see how you go

Check your printer settings to make sure the print in b & w box is not selected. Hope this helps.

Have you tried a new GENUINE Panasonic Toner Cartridge?

You are lucky you can print ANYTHING! My unit has NEVER worked (3 years) due to a hardware defect of HP. I downloaded patches, cleaned/replaced cartridges, etc.
Spoke to HP last nite-Was told printer was junk-they don't carry it or any parts to fix it anymore!! I was told to replace it!

REPLACE PAPER AND THE INK CARTRIDGE
