After setting up a few users on yet another HP Laserjet P4015dn, one person complained that when they told Microsoft Word to print 10 copies (or any number, really) only 1 copy would actually print. The printer wouldn’t report any errors, and neither would the computer – everything would just report normal.

A closer look revealed that the printer driver had Mopier Mode enabled. As per HP, this mode is used when the printer has an EIO hard disk installed. If the printer doesn’t have one, it will only print one copy. To disable Mopier Mode, do the following:

  1. Open the (Devices and) Printers Control Panel.
  2. Right-click on the printer, and choose (Printer) Properties.
  3. Click the Device Settings tab.
  4. Scroll to the bottom of the list, and change “Mopier Mode” to “Disabled”, then click OK.

Easy, right?

TL;DR Version: If your HP Printer is only printing one copy when told to do more, make sure Mopier Mode is disabled in the Printer Properties.

Recently, I installed a nice shiny new HP Laserjet P2055DN for a few administrative employees, replacing a horribly old Lexmark T612 that had been knocking on death’s door for a few years already. The install went off without a hitch, however I was getting scattered reports of documents printing on Legal-sized paper instead of Letter, and some jobs that just refused to print, insisting that the user needed to put paper in the manual feed tray.

I tried to reproduce the problems on my machine, but never could, and the user who was experiencing the problem was frequently away from her office, so it was difficult to see what was going on.

Finally this morning, it happened to her again just as I happened to be walking by. A quick inspection of the printer settings told the story. Apparently, her computer (and her’s alone) was defaulting to the A4 paper size, which is slightly different from Letter. As a result, it would ask for it to be loaded through the manual tray and, failing that, print on Legal instead.

Figuring this would be a simple fix, I went in to the printer settings and tried to modify the default preferences. No dice. HP marks the defaults as read-only and won’t let you change them. Any attempts to set other areas to print to Letter as default would simply result in them being returned to A4.

At this point, getting rather fed up, I started digging through settings trying to find what was different on her computer – after all, the four other computers printing to that printer were working fine.

At last I stumbled upon the culprit – the Regional Settings. Every other computer in the office had it’s location set to the United States, whereas her computer had the location set to Canada. As soon as I changed it (no restart required), the HP drivers immediately defaulted to Letter instead of A4. Problem solved.

So thank you, HP, for not letting your users pick there own defaults and assuming that Canadians only us A4-sized paper. I bet you think we all live in igloos and say ‘aboot’ instead of ‘about’ too, eh?

I ran in to an issue the other day at work. We have three tape backup units serving ten servers, two Seagate DDS4 DAT-72 drives that are around four years old, and an HP Ultrium 2 purchased earlier this year.

Over the last three weeks, the cleaning lights on the Seagate drives started lighting up on a daily basis. I tried running the cleaning tapes three times in a row for a few days, and even replaced the cleaning tapes, but there was no difference.

A little Googling suggested that the drive heads were likely wearing out, but I wasn’t ready to give up on the drives yet. Taking a page out of my NES repair guide, I lifted the flap on the front of the drive and blew in. After getting a mouthful of dust, I repeated the action and then did the same on the other drive.

Since then both drives have gone back to only requiring a weekly cleaning. Who says the Nintendo Generation has contributed to troubleshooting?
