HP 4250TN running slow

[yormets]

Anyone seen a 4250TN suddenly start running about half speed when printing? It's not the network as the customer has several printers and the problem follows this printer. I've checked the paper settings and changed the formatter. Same result. It warms up at normal speed, but prints slow. Any ideas?

What driver are you using?
I recommend you use the PCL5.
The PCL 6 and universal driver have a lot running in the back ground and will slow things down.

I don't know. They have several printers. It only effects this one printer no matter what station they put it at. Same driver is driving all their printers. This one suddenly started running slow. It's not a network issue. It's in the printer.

Then its time to upgrade firmware.

Isn't the firmware in the formatter? The firmware upgrades the DC controller?

Its may be set on custom blue lever on actual tray

[HP:guy]

The firmware loads on to the format board.

It is usually the custom lever in the tray not hitting the the switch correctly also check in the menu under print quality, fuser mode ,plain it is set to normal not heavy 2
