Error 61:01 wrong file format. The printer cannot process the job.

This can happen due to the firmware on the plotter, even if it happens only with some postscript files.

The "file format is incorrect and the printer cannot process the job".
But you already knew that.
Is it ALL jobs that get this error?
If it's just the one, it could be corrupted

Power off from the back of the printer. Disconnect the power cord.
Reconnect the cord and power up.
Check the "graphic language setting"...refer to the user guide.
Resend the job to the printer.
Make sure that the firmware is up to date.
Upgrading the firmware will re-install the PostScript fonts.
The file you are trying to print could be password protected. Resend job without password protection.

Did it ever work?

You are using the Post Script drivers, right?
Power down the printer from the back. Disconnect the power cord. Plug it back in and power it up.
Check the graphic language setting of the printer(look at the User Guide)
Resend the file.
Upgrade the firmware to the latest version (www.hp.com/#support)

Try HP Support & Drivers.

There is probably nothing wrong with the printer, but it may not be be receiving all the dope it needs. Usually the printer needs a CR/LF signal at the end of the file to print. If it doesn't get that it will assume that it hasn't got all the file and will hang. This may be a setting in the application producing the file, or a setting on the printer itself (i.e needing either a full CR/LF signal or just one of these). Don't like the idea that it doesn't print its own test page though....

The problem is usually caused by printing a PDF file with fonts/page size/ page formating errors which will cause the printer to display the 49.3048 error. The only way to use the printer is to POR or recycle the power and delete the print job from the server or spooling device and cancel it on the printer before the offending command is issued to the printer again. You can try updating the firmware to the latest version 46.140.5 from the HP website. MIke L.

Check the amount of RAM in the Printer using the Front Panel buttons.
install more memory into the Formatter or
try processing the file in the PC instead
of the Printer (select Avoid out of memory in Advanced options in the driver)
good luck.

I'll have to call tech support on this one but I have a feeling that the job is too big for the copier to convert into a pdf file and send it out. It could be cause by lack of printer memory to handle the job. If the copier is hooked up to a fiery controller, then it would work because it has enough hard drive space to process it. You could try changing the format from pdf to another file format and see if that works or break the run up into two jobs.
