HP Designjet 430 "out of paper" message on computer when it is not out of paper. help please

Check and see if the carriage moves freely from left to right (with power off). If not, make sure the carriage belt is good & the rails it slides on are clean and properly lubricated (light oil).

The paper is detected when the carriage moves over it to determine how wide and how long the sheet is...if the carriage isn't moving, then it says no paper.

It could also be that the line sensor on the carriage is dirty or defective and can't "see" the reflection from the paper. If cleaning the sensor (it is on the RH side of the carriage) doesn't resolve the problem, then the sensor would need replaced, if it is still available that is...

I recently replaced the belt in my HP 450C plotter. I hadn't used it in about a year but I put new ink in too. I got one really light test page and now nothing. The print head tries to do the job and there...

it is possible that all the printheads have dried up .try dabbing a wet tissue on the bottom of the printhead,if this does not solve the problem then you need to replace the printheads

How can I replace the belt for the ink carriage

Here is an HP Support Forum where a user has posted a detailed procedure for the belt replacement.

The Service Manual is needed. It's available at:
Designjet 430, 450, 455C - Service Manual
DesignJet 430, 450C, 455CA - Quick Reference Service Manual

As mentioned, it's a delicate and time consuming operation. I replaced my belt two years ago with little problem. (Be sure to clean the old degraded belt gunk off the drive pully too!)

It's not a job for "Beginners". More like "Intermediate" or "Advanced".

Good Luck!

This is the part I ordered. It was $15
If you have the smaller one, you must research the part number for that.

Replacement carriage belt for HP DesignJet 800

The part number is; C7769-60182 runs at around $70.00.
This component needs to be installed by a service technician. You can seriously damage this plotter if you remove the carriage ribbon connectors and do not install them properly. You will fry the pca board (a $1,100 mistake).

Hp designjet 430

This usually is solved by removing and reinstalling the ink cartridges...make sure the electrical contacts are clean (use a dry paper towel) on both the print cartridge and the carriage.

If the error still happens then the carriage or trailing cable are bad and will need replaced.
