you can turn off print summary by accessing printer menu , one of the function

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,.

There is a paper feed sensor located behind Tray 1 where the tension spring gets knocked loose, therefore the sensor arm is still blocking the sensor. You have to remove all covers and the Tray 1 Assembly and re-install the spring which goes into a slot on the plastic frame.

Remove the memory.
Pull out the formatter cage
Remove the network card

Reinstall all items removed

go to the File menu of the application you are using, then click Print Properties or Page Setup. From there, you may adjust the left and rught margins.

attempt to clear the print spool and set the its settings to print directly to the printer. Do a test print, then enable print spooling again. If the same thing happens, uninstall and reinstall the latest printer driver

try assigning a different IP to it and see if it can be ping afterwards. If the same thing happens even with different IP, chances are, its NIC is defective and needs to be replaced.

the reason why i ask that because if the fold looks like its been pressed then its before the fuser but if its loose than its after. And thats how we can determine where it begins

Set to Print directly to printer.

General printer error. Unplug the power cord for 10 seconds.

Set it in JetAdmin.

It sounds like the registration switch actuator is being held down too long.

Also check registration clutch and make sure cassette tray is lifting all the way up and feed rollers are "snapped" in tight. Good luck.

Weird problem!

You will find the answer in Printer properties.

I think you have to turn off auto select.

Your fuser element is faulty. Check both connectors, make sure they are nice and secure on the element. Still not working replace element.

Error 51 is a fuser error. The fuser needs to be replaced. And, please take a moment to rate this solution with a fixya rating. Thanks! :c)

Hewlett Packard printers can have their serial numbers reprogrammed in the field, from the front panel of the printer, with very little special knowledge and no special tools. Any electronic page showing its serial number afterward would be divergent from the actual serial number for the machine. It can be changed back again, too - an unlimited number of times.

Yeah, I know - you'll never trust the page count on a used printer again, but there you have it.

This is only true on some of the newer models, and on the larger ones - not the smaller machines like the 1200, but the larger ones like the 5Si, the 4500, etc.

Canon builds the print engines (basic mechanical arrangements of components) for Hewlett Packard, which only really engineers the firmware - which could be used to implement the hidden codes you're investigating. But I would not be surprised if Canon and HP codes look the same and are implemented at a level common to both brands of machine. It is odd to me that you did not publish any pictures of the test prints from the manufacturer which dominates the industry, though...

Since you can alter the serial number (at will) on an HP machine, that could make your decoding task that much easier, if you have access to one. Set to all 1's, all 2's, etc. and compare test prints.

On the other hand, it also makes the entire schema a joke, since I could program my printer to say it is your printer (copy your serial number), print up some phoneybux, and then set it back to innocent_serial and whistle while I watch your office get raided.

The serial number information is soft-coded to allow the formatter board to be replaced if it fails, while still supporting the configuration page's reportage of that printer's vital stats. You can even load the new formatter with the page count from the old formatter, so that the mechanical parts can be maintained on schedule as they wear out.

Now, this is not true of the Formatter Number, which is the serial number of the formatter card itself. If that is the basis of HP's system of Identity, then the workaround would involve a physical removal of the formatter and its (temporary) replacement with another formatter. For someone engaged in producing phoneybux, this is not an economic hardship.

If the printer is processing jobs slow,  especially for PDF's before they come out of the printer  it's probably a printer memory issue. To test, send the print job at a lower resolution. If that works then you can just print jobs at that resolution or install more memory.  If the print jobs are coming out of the printer slow then your printer settings may be set to the highest resolution of pro res instead of the default fast res which cuts the printer speed in about half.

I think your best bet is just to store the old lid away and keep the receipt that HP sent with the new lid. That way you can prove they replaced the lid and you have the old one with the sn on it to prove it.

Good Morning,
First off there is a chance that the piece is still floating around in the machine or in the box it came in. Pull out the Toner, Fuser, Tray and tilt the machine see if you hear anything rattling around. Now on to your questions.
1) You can not order this part by itself. It could be part of the big chassis piece that the transfer roller fits into.
2) There are two V shaped tabs on both sides on the guide that hold the piece you lost in place. Now if these are broken then it will not a new guide in place.

The best way to get the machine working is to either rigg it, or a better option might be to call around your area to printer repair places and see if they have any dead 4200, 4250, 4300, or 4350's.
They will all use they same part. So will the 4345 MFP series. Any shops that do in shop repair usually have more machines sitting around.
Hope this helps
