Laserjet Testing

Procedure

• Identify model series

1. If it is HP 2000+ series continue testing
2. Otherwise, junk it

• Examine and determine if all necessary casing/components are attached

1. Use common sense, such as: "If I saw this printer would I want to buy this as is?".
2. If it looks like junk, then junk it.

• Locate Toner Cartridge

1. Typically located under a top-front panel, if you can't locate it immediately just root around in the panels. If you still can't locate the toner ask for help or assume the toner is missing.
2. Does it appear to be damaged or leaking? If not:
   • Replace w/ necessary component
   • Otherwise, junk it

• Locate Paper Tray

1. Replace small amount of paper

• Check for errors on display

1. Is the error physical/mechanical?
   • If problem is easily repaired, such as a paper jam, repair.
   • Otherwise, junk it
2. Is the error software?
   • If you know exactly what the problem is, great. Otherwise, ask for assistance and determine whether or not the problem has an easy solution. If the problem doesn't have an easy solution, such as a "Memory Error...", junk it

• Locate ports

1. Attach necessary connections
   • Power, parallel, CAT, etc... are typically located under the larger work tables.

Instructions for printing in Ubuntu:

• Connect via USB or LPT to one of the testing machines. If you're using LPT, check to make sure there is a switch and it's set correctly.
• If you're using USB, Ubuntu should autodetect the printer. Print a test page.
• If the printer isn't autodetected go to System > Administration > Printing and add a new printer. Be sure to follow the recommendations made for driver selection and options. Get help if you hit a snag. Then print a test page.
• Delete the printer profile from the menu when you're done.

Instructions for wrapping and sending off

There are several things we need to check with a Laserjet before we can sell it or give it away:

1. Print an Ubuntu test page (to package with the printer).
   • Include:
   1. A brief description, such as: "Tested and works."
   2. Any new/replaced toner
   3. A date
2. Make sure it has all of its covers and, if applicable, paper trays.
3. Make sure it has some working toner in it.
4. Make it somewhat clean.
5. Include a power cord with it.
6. Have a coordinator check it off.

How we get through this checklist is a little imprecise. Here are some resources.

1. We keep some toner, marked by model numbers, in boxes under the testing bench:
2. We keep some parts, in specially marked boxes, on the shelves.
3. There are numerous online resources for error codes on the internet, including in the Printers sidebar.

Disposal

• Locate Network Interface Card(NIC)

1. Is it an add-on parallel or 10 Base-T card?
   • Remove and place in NIC bin for further testing.
   • Otherwise, disregard the card.

• Remove

1. Paper from all trays.
2. Toner Cartridges
   • Carefully inspect area surrounding cartridge for leaks and vacuum remnants of toner(s).
   • Place cartridge in bin marked for toner disposal. If you're unsure as to where this is ask for assistance.
