Re: AR-207 copier has "CH" flashing what to do?

CH code is usually associated with the Crum chip located on the back of the toner cartridge that gets 5 volts dc from the power supply and resets a counter on the main board to tell the copier approximatley how much toner you have when you insert an new toner. What may have happened, is the same 5 volts dc is shared with the laser unit and the when the laser goes bad it may cause the CH code just before it gives the E7-03 code for the laser due to the 5 volts being drawn down by the bad laser. If turning the machine off and back on with the new toner doesn't fix it then you either have a bad chip on the new toner or a bad LSU (laser Scanner unit)

Toner explosion

You need to either replace the toner cartridge or empty the sump on the front of the cartridge. The waste sump is in the front of the toner cartridge, It has filled up and has nowhere else to go but out of the sump and where ever it lands. Sometimes they fill up before the toner cartridge is empty. It happens

Crum data read trouble in sharp ar 207

The CRUM chip is what tells the copier that the correct toner is installed. It is specific to the toner cartridge. If it is a new cartridge then it should have a new CRUM chip and there should be no problem. If it is a recharge it's possible that the chip was not changed or the wrong one was used.

Error code.

CH error has to do with your sorter. Check to make sure it is connected properly and see if there is anything jamming inside of it.
