SOURCE: error code 14 "no tuner cart"
14 NO EP CART Message
The printer detects the presence of the Toner Cartridge and the
level of toner present in the cartridge through the condition of the
ANTIN signal. The ANTIN signal becomes part of the serial data
stream used to communicate with the DC Controller (see Figure
7-5 for cartridge components). Troubleshoot the 14 NO EP CART
(or INSTALL TONER CARTRIDGE) message as follows:
1 reseat the Toner Cartridge. Try a new or known good Toner
2 Check the High Voltage Contacts for damage. If the contacts
are dirty or damaged, clean the contacts after the repair.
3 Replace the High Voltage Power Supply.
4 Check and reseat the HVPS cable.
5 Replace the DC Controller

1. Reseat the cartridge. Try a new or know good cartridge. If OK, stop.
2. Check the Hi Volt contacts on the cartridge for damage. If the contacts are dirty or damaged, clean the contacts after the repair.(This is especially important if the cartridge is recycled.) If OK, stop.
Before going further, evaluate the cost effectiveness.
