• Code: 49.XXXX
• Display: 49.XXXX PRINTER ERROR
• Description: A critical firmware error has occurred that caused the processor on the formatter to abort operation. This type of error can be caused by invalid print commands, corrupt data, or invalid operations. In some cases, electrical noise in the cable can corrupt data during transmission to the printer. Other causes include poorquality parallel cables, poorconnections, or home-grown programs. On rare occasions, the formatter is at fault, which is usually indicated by a 79 Service Error.
• Remedy: 1 Press CANCEL JOB to clear the print job from the printer memory. 2 Turn the printer off and then on. 3 Try printing a job from a different software program. If the job prints, go back to the first program and try printing a different file. If the message appears only with a certain software program or print job, contact the software vendor for assistance. 4 If the message persists with different software programs and print jobs, disconnect all of the cables to the printer that connect it to the network or computer. 5 Turn the printer off. 6 Remove all memory DIMMs or third-party DIMMs from the printer. 7 Remove all EIO devices from the printer. 8 Turn the printer on. 9 If the error no longer exists, install each DIMM and EIO device one at a time, making sure to turn the printer off and on again as you install each device. 10 Replace a DIMM or EIO device if you determine that it causes the error. 11 Remember to reconnect all of the cables that connect the printer to the network or computer. 12 If the error persists, replace the firmware DIMM. 13 Replace the formatter and calibrate the printer.

• Code: 50.X
• Display: 50.X FUSER ERROR
• Description: A fuser error has occurred.
  X Description: 1 low fuser temperature o 2 fuser warmup service 3 high fuser temperature 4 faulty fuser 5 inconsistent fuser 6 open fuser 7 fuser pressure-release mechanism failure
• Remedy: 1 Turn the printer off and allow it to cool down. 2 Reinstall the fuser, and check the connector J4034 that connects the fuser and the printer. Replace the connector if it is damaged. 3 Turn the printer off and remove the fuser. Measure the resistance between the connector pins on the fuser. If resistance does not meet the following guidelines, replace the fuser. • J4034-5 to J4034-6: 300 - 500 KOhms • J4034-1 to J4034-2: less than 1 KOhm 4 Check for continuity between connector pins J4034-4 and J4034-2. If no continuity exists, replace the fuser. 5 Replace the fuser power supply PCA. 6 Replace the DC controller PCA. Calibrate the printer after replacing the DC controller.

• Remedy: 1 Press to continue. 2 Turn the printer off and then on. 3 Reseat the connectors between the laser/ scanner and DC controller PCA (J1009 - J1012). 4 Replace the defective laser/scanner assembly. Calibrate the printer after replacing the laser/ scanner. 5 Replace the DC controller PCA. Calibrate the printer after replacing the DC controller.

• Code: 53.XY.ZZ
• Display: 53.XY.ZZ CHECK RAM DIMM SLOT
• Description: An error occurred in some printer memory.
  X DIMM Type: 1 Slot 1 2 Slot 2
  Y Device Location: 1 DDR Slot 1 2 DDR Slot 2
  ZZ Error Number: 0 unsupported memory 1 unrecognized memory 2 unsupported memory size 3 failed RAM test 4 exceeded maximum RAM size 5 invalid DDR speed
• Remedy: NOTE The HP Color LaserJet 4610n printer has only one DIMM slot. 1 Turn the printer off. 2 Verify that the memory meets specifications and is correctly installed. 3 Turn the printer on. 4 If the problem persists, replace the DDR card in the slot indicated.
