PRINTER ERROR

To continue

turn off then on

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 poor-quality parallel

cables, poor-connections, or home-grown

programs. On rare occasions, the formatter

is at fault, which is usually indicated by a 79

Service Error.

1. Turn the printer off then on.

2. Press Stop to clear the print job from

the printer memory.

3. Turn the printer off then on.

4. 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

displays only with a certain software

program or print job, contact the

software vendor for assistance.

5. 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.

6. Turn the printer off.

7. Remove all memory DIMMs or thirdparty

DIMMs from the printer. (Do not

remove the firmware DIMM.)

8. Remove all EIO devices from the

printer.

9. Turn the printer on.

10. 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.

11. Replace a DIMM or EIO device if you

determine that it causes the error.

Hello and Welcome

Fault(error) 49 is a critical firmware error which cause the processor on the formatter to abort operation.This type of error can be because of invalid print commands,corrupt data,or invalid operations. Sometimes electrical noise in the cable can corrupt data during transmission to the printer. Other causes include poor quality parallel cables or poor connections,
To solve this try this solution step by step:

• Turn the printer off and then back on.
• Try printing a job from a different software application. If the job prints, go back to
• the first application and try printing a different file. If the message appears only with a certain software application or print job, contact the software vendor for assistance.
• f the message persists with different software applications and print jobs, disconnect all cables to the printer that connect it to the network or PC.
• Turn the printer off.
• Remove all memory DIMMs or third-party DIMMs from the printer. (Do not remove the firmware DIMM in slot J1.)
• Remove all EIO devices from the printer.
• Turn the printer on.
• If the error no longer exists, install each DIMM and EIO device one at a time, making sure to turn the printer off and back on as you install each
• device.
• Replace a DIMM or EIO device if you determine that it causes the error.
• Remember to reconnect all cables that connect the printer to the network or computer.

If the error persists, final option is replace the firmware or best & final option is to just contact to any HP service provider

I hope this solution will be helpful for you.

Having the same problem here... very random... send a print job of labels and it will print the whole lot, or freeze at random points but always halfway through a label... no error message... unplug usb and replug doesnt do anything, but unplug and replug power and off it goes printing more lables but may even freeze again after only a few more have come out... also, every day the first print job of the day prints half the label and pauses for about 10 seconds then keeps going...

had printer for approximately 2 years. Used daily in office setting. today the printer tried to print, then just stopped and it said fatal error 17H in the window. We cleared paper jam and rebooted, gives the same error message. Anything we can do?

he printing operation has been aborted.
The issue can be caused by a firmware error, invalid print commands, corrupt data, invalid operations, poor quality parallel cables, poor connections or specific applications.

Action :

1> Press Cancel Job to clear the print job from the printer memory.
2> Turn the printer off and then on to clear the error message.
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,.

Hi,
I have come accross this problem on a number of sites. It may be the Paper Out sensor. It works by emitting light from one half of the sensor reflectiong it of the paer and picking it up with the other half of the sensor. When no paper is present, the light cannot reflect and hense a paper out error is reported. I have seen this error occur when paper with dark backing ( like that for bank and tax forms ) is used.
