By it going back and forth means all is ok with the encoder strip. Sounds like its asking for a bit of lubrication. There is a special oil available from HP for the carrage. This also works for tha large format machines using plastic bushes such as 500, 800, T610, new 510 etc.

750c plus was turned off and now says printer cartridges missing


Pull out the cartridges, turn the plotter on and install the ink cartridges one at a time - making sure each one is recognized. One of them may have gotten a power surge and had the electronics burned out - - replace that cartridge with a new one.

Everytime I turn on the designjet 750c plus, it tells me to turn power off and check cartridge path.


Make sure you have the correct cartridges and that the tape has been removed.
You can try a new set of cartridges and see if that solves your problem.
I hope this helps.
Have a good day and good luck.

My HP750 plotter just displayed the message, "Switch Power Off; Check Cartridge Path" after the last print job. I see nothing blocking the printer cartridges and can't get the message to clear. Am I...


I've seen this error on the Designjet 750 plotters. Basically the plotter puts out this error if the carriage assembley cannot move along the Y-Axis (back and forth)
The carriage moves along the Y-Axis driven by a motor with a metal gear, pushing and pulling a rubber belt. Over time the interaction between the metal and rubber causes the teeth to wear off the belt and often times the worn rubber gets stuck in the teeth of the motor gear.
So, open the cover, and look behind/below the carriage itself and find the belt which runs the width of the printer. Run your fingers along the tooth side of the belt and check for degraded teeth, aslo examine the metal base below for any debris If you find debris, this is your root cause of the error you are getting.
Unfortunately, changing the belts on these machines is quite a process; on average it takes me 3 hours to replace a belt (and I've done dozens of them) It would be best to find an experienced tech since there can be some difficulties when replacing the belt (specifically proper belt alignment, and the removal of the side covers can be tricky as well.)
If you do not have any debris, and the belt is degraded, it could be that the motor which propels the carriage could be bad or something is obstructing the movement of the carriage head (the ink supply lines, the pen path, or media could be the issue).

DesignJet 750c Plus System Error 040502


The bad news is that this seems to be a fatal error of the main board. The only time I have had a similar error is when the carrage motor shorted out and blew the main board. This probably did not happen in your case but something appears to have taken the board out. The main board is speculation, but I think I am correct, sorry, Dave

Sounds like it can not find home. Is there a limit switch? If not there may be a failure in the counter from the stepper motor.

HP 755 CM CARTRIDGE MISSING ERROR


This normally points to a worn ribbon on the carrage. Make sure the ribbon where the cartrige makes contact is really clean, if cleaning make sure the plotter is turned off. Sometimes a build up of ink can cause problems. The bad news is that if the ribbon on the carrage is worn it firstly comes with the carrage as a unit, and secondally the carrage is no longer available from HP

Printhead


When the plotter goes through its initialization, it stops, the printheads move to the right side and the window displays "switch power off, check printhead path (2)" I've turned the power of an wiped things down, I've unplugged and then restarted but continue to get this message. What do I need to look for or do to get it back on track?
