You can turn off F5-25 in a pinch if you need to wait on parts.

just to add that when the copier is allowed to operate under low toner (u13) condition, developer is depleted quickly , and when toner is replaced, the machine will overtone and results in a dirty machine. We have converted all high speed 35xx-60xx series copier back to using OEM toner. This drop the frequency of e3/40 calls to almost zero. If youb are using katun or densi toner , be sure to leave a spare bottle and change the function to " STOP" when toner is out.

1. Clean inside the machine
2. Change the developer if needed
