Hp color laserjet cm1017 mfp 49 service error showing in disply screen and restart the printer

49.XXXXX ERROR To continue turn off then on

A critical firmware error has occurred.
This type of error can be caused by invalid
print commands, corrupt data, or invalid
operations.
In some instances, electrical noise in the
cable can corrupt data during transmission
to the MFP. Other causes include poorquality
parallel cables, poor connections, or
specific software programs.
Sometimes, the formatter itself is at fault,
which is usually indicated by a 79 ERROR
message.

Follow this:

1 Turn the MFP off, and then turn the MFP on.
2 Upgrade the firmware.
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 when using different software programs and attempting specific print jobs,disconnect all of the cables that connect the MFP to the network or a computer.
5 Turn the MFP off.
6 Remove all DIMMs and flash-memory cards. Do not remove the firmware memory card that is in slot 1.
7 Remove all of the EIO devices.
8 Turn the MFP on.
9 If the error message disappears, reinstall each DIMM, flash-memory card, and EIO device individually, making sure to turn the MFP power off and then on again as you install each device.
10 Replace the component that caused the error message.
11 If the error persists, replace the formatter.

Try the following: got to the menu (the wrench) and with the arrows look for service, press ok and look for restore defaults. After that unplug the fax line (this is very important). Go to the hp website and download the firmware update and run it (while updating dont to anything to the printer, no print, copy, fax.) when that is completed try to fax again this should resolve it. If not I recomend to contact a service center, it could be the formatter (the motherboard)

this is the firmwere error pls turn off the printer up to 30 min then on if problem persiste replace the formatter cart ur problem will be resolved

a 49.xxxx error on an HP means that there is an issue with one or more hard disks. you can try to re-initialise the hard disk(s) by rebooting the printer while holding the green button. when the three leds are lit, release the green button, and navigate using the numerical buttons until you see "initialise hard disks" on the display of the printer. confirm by pressing the green button again. if all goes well, your printer will take two minutes longer than usual to boot. if you still get the same error afterwards, you need to replace the disk.
