My HP laserjet 1200 series laser printer is now printing all pages with a grey background from the toner covering the whole print area. I can still see the printed letters as much darker, but this gray wash across the whole background looks bad.
I can think of two possible causes.
First, my replacement toner cartridge for the c7115a Toner Cartridge was a compatible one sold by imagestore us inc, perhaps the cartridge is defective or after market ones are not worth using? I took the cartridge out and rotated around the long axis several times back and forth, but the printing was no different.
Second, I recently moved, could some damaged have occurred during moving (I replaced the cartridge right before moving and do not recall if this issue existed before moving.)
If it is the first, I just buy an official HP cartridge, if not, I get a new printer.
