CM4540 prints slow

[1stsadman]

So my HP CM4540 now prints very slow. prints first 5 copies off very fast then goes to a crawl 1 sheet every 20seconds , my inkjet prints faster.

Ive reinstall drivers

I've Factory resett the print (now this works but after about an hour the the problem comes back)

Install HP Universal print driver PCL6 and try printing with them.

A way to determine if you have an issue with the printer or with the driver or your network is to make 50 copies of a document or use the print test in the troubleshooting menu to print 50 pages. If you get the same slow down making copies then you have a hardware issue. if the 50 copies come off fine, then as posted by @Valsimot you likely have either driver issue or possibly a network issue that is bottlenecking your print speed.

Hi thanks 

The printer will do photocopies no problem 

Do I know it's a driver/ software issue

Have uninstalled driver/software and then installed universal pcl6 driver and one computer works well but the other 2 computers still print 5 then 1 sheet every 20 seconds

Are the workstations printing direct to the printer or through a print server?

ive uninstalled the HP software and then installed  the universal PCL6 driver.

nothing changed still printed  the first 5 copies nice and fast and then 1 sheet every 20 seconds.

interesting tho i did a factory reset and  then printed the same document  perfect and fast  but the next day  printed the same document again same old thing first 5 copies fast then 1 sheet every 20 seconds

they do the same via usb printer cable or over network, the document is 1 page  but need 50 copies , so does the 1st 5 copies really fast then slows 1 copy every 20seconds

printing from the printer ie copier and reports everything is fine its when you print a document or page more than 5 copies it seems to struggle. 1st 5 sheets come out fast then 1 sheet every 20 seconds even when its a single page document and you need 50 copies  it does the same

recent development .

I have uninstalled all the hp software from one of the computers and the installed the PCL6 universal driver.

went to print document 1 page 50 times same thing happens 5 sheets in slows down, but when i sent to manual tray (tray 1) no problem prints nice and fast, 

does that mean its the PC or Printer?
