Question about Sharp AL-1642CS Copier
The letters "CH" are blinking on the screen and it won't print anything.
On the Sharp copiers when the "ch" is blinking means that the toner cartridge is not in or it may be the wrong cartridge. Some sharp cartridges look alike and will fit into the machine but are the wrong one.
Hope that helps...
