Question about Office Equipment & Supplies
Sharp al-1644 is showing code CH.
How do we clear this and get it working?
Usually CH indicates that one of the doors on the copier is not closed properly, if it is a flashing CH then there is no toner cartridge in the copier or the cartridge is of the wrong type for this machine. A lot of toners for this machine look alike but are not the same for the machine.
