I use to order, deliver, replace, install, setup and configure LAN and VLAN and break fix (repair) HP Laser Network Printer on Enterprise Domain. So this model you have: Below is the rated output volume of pages this printer can handle.
[FONT=Arial]Recommended monthly print volume 3000 to 12,000 pages[/FONT]
If your department is printer higher volume of print jobs per day that exceed that total below then your department heads needs to be in a service order request for higher volume printer. As this one can't support your department.
I had one department at Health-net that had the same issue. I had to order higher volume network laser printer. Cost was extremely high but the end results was the department was more proficient than they were sitting there waiting on print jobs to complete.
No this is not a permission issue it's the printer can't handle the volume of print jobs. Whoever order this printer didn't take in for account how the department print job demand would be higher volume.
This needs attention ASAP!
If your department is doing 9,000 sheet per day or higher this printer can't handle those volumes and your lucky it hasn't started to break-down.
By-the-way this model is it on a table or it's it on 4 wheels with extra bay trays.
