Display: Stack over and under flow error; code error.
Description: Never error
Remedy: Unplug the printer from the electrical outlet, wait for 10 seconds, and then plug the printer back in. If the problem remains, then replace the printer. Service: Replace the system board.
Code: 44
Display: An error condition was detected in the software control code.
Description: Software detected error
Remedy: Unplug the printer from the electrical outlet, wait for 10 seconds, and then plug the printer back in. If the problem remains, then replace the printer. Service: Reinstall the print driver. If the problem remains, then replace the system board.
Code: 45
Display: Error detected that a while loop or similar loop timed out before the event it was waiting on finished.
Description: Loop timeout error
Remedy: Unplug the printer from the electrical outlet, wait for 10 seconds, and then plug the printer back in. Service: Replace the system board.
Code: 46
Display: Indicates that the control section of NVRAM is corrupted.
Description: NVRAM control section corrupted
Remedy: The printer will auto reset.
Code: 47
Display: The printer carrier has stalled.
Description: Print carrier stall
Remedy: 1. Check if the ink cartridges are properly installed. 2. Clear the jam clearance area from any obstructions. 3. Unplug the printer from the electrical outlet, wait for 10 seconds, and then plug the printer back in. If the problem remains, then replace the printer. • The carrier slams against the side frame. • There is no carrier movement. • Check the encoder strip for proper installation. • Check the carrier cable connections J21, J22, and J23 on the system board. If the cables are connected, then make sure that the encoder strip is clean. Clean it with a damp cotton swab. If the problem remains, then replace the system board. See “System board removal”. • Check the carrier transport motor connector J1 on the system board. If it is connected, then check for approximately 30 V dc on pins 1 and 2 or at the wire connections located on the rear of the carrier transport motor. If voltage is incorrect, then replace the system board. See “System board removal”. If voltage is correct, then replace the print engine. See “Print engine assembly removal”. Carrier transport motor does not operate. Check the carrier transport motor connector J1 on the system board. If the cables are properly connected, then check for approximately 30 V dc on pins 1 and 2 or at the wire connections located on the rear of the carrier transport motor. If voltage is incorrect, then replace the system board. See “System board removal”. If voltage is correct, then replace the print engine. See “Print engine assembly removal”. Paper feed motor does not operate. Check the paper feed motor connector J3 on the system board. If it is connected, then check for approximately 30 V dc on pins 1 and 2. If the voltage is incorrect, then replace the system board. See “System board removal”. Although the paper feeds turns in one direction, the paper feed motor turns in two directions. If the paper feed motor turns in one direction only, then replace the system board. See “System board removal”. Poor print quality • Be sure that the printer contains good print cartridges. • Be sure the print cartridge nozzle plate is clean. Clean with a lint-free cloth, wiping along the direction of the nozzle. Ink smudging and smearing can be caused by paper problems or problems in the paper feed area. Check for: • Correct type of paper • Curled or wrinkled paper • Paper path obstructions • Paper pick roller wear or looseness. If the paper pick rollers are defective, then replace the print engine. See “Print engine assembly removal” on page-39. • Worn gears or binds. If the gears are defective, then replace the print engine. See “Print engine assembly removal”. Blurred prints and voids can be caused by problems in the carrier transport area. Check for: • Carrier transport belt and idler pulley parts for wear, damage, or looseness. If the carrier transport belt is worn or if the idler pulley parts are defective, then replace the print engine. See “Print engine assembly removal”. • Carrier shaft for wear or dirt. If the rod is dirty, then clean and lubricate it. The carrier to carrier frame engagement should be lubricated with grease P/N 40X0179.
