The encoder strip in essence lets the carriage tell the electronics module where it is over the paper or in the ends of the plotter.

I need a hard drive DesignJet 5000 and 5500

Has this ever happened to you?
You turn on your DesignJet 5000 or 5500 model plotter and before it comes to the ready prompt:
Error 1f500XX (boot failed) or e50000?
Both errors are related to a failed or improperly connected hard disk drive.
So you follow the troubleshooting tips in your trusty manual only to find out your hard disk has gone caput, trashed, fried, no longer in this world, DEAD.

What to do now?
Order a new one.
Well that could be an issue, you see in the past two years our friends at HP have stopped producing them. The original hard disk that shipped in your plotter when it was new was a PATA or EIDE hard drive, HP changed that and started shipping a replacement SATA drive with an adapter kit. But no more.
The drive kits:
DesignJet 5000:
C6090-60344 for RTL (non-postscript)
DesignJet 5000 PS:
C6091-60268 for Post Script

DesignJet 5500:
Q1251-60323 for RTL (non-postscript)
Q1252-60045 or Q1252-60054 for Post Script

All of these hard drive kits have been discontinued and are no longer produced by HP.

Clearing Paper Jams in InkJet and DesignJet Printers

Field techs have used this old trick and it is time to share.

When your inkjet type printer displays a Paper Jam error and you cannot see any paper in the path, anywhere. You may have a small torn away scrap of paper somewhere in the path. This usually occurs after you have experienced a feed problem and had to manually pull the paper out of the printer.
Use caution whenever you must manually (and forcefully) yank out a piece of jammed paper.
Pull the paper from both sides using both hands and use a slow, even steady motion. Don’t do what I do and put on foot in the printer and yank as hard as you can.
A small scrap may tear off the paper and remain lodged in the paper path, usually where you cannot see it and with my luck, about an inch away from where your fingers can reach.
