Hi all: Have a Designjet 500 which hasn't been used in awhile.. Needed a carriage belt, which I replaced, and now is giving a 21:10 error. Machine has gotten very little use, very clean. The carriage goes to the extreme left, then to the extreme right, then moves about 1" past the service station and pops the error. Sometimes there is a small grinding noise coming from the service station. I replaced the service station with a new one, and still has the same exact problem. All the research I've done says it's the service station, but two doing the exact same thing? And one of them new? Seems unlikely.... anyone had this issue? Thanks Jeff M.

Re: DesignJet 500 21:10 error
The 21:10 is a Service Station error. Most often what happens is that the ink in the service station (aka printhead cleaning unit) hardens up, and the mechanical aspects can't turn. You said that you installed a new service station. Was it a slightly used service station that had not been used in a long time?
I've fixed a few of these service stations by carefully disassembling the service station, and scraping out as much of the putty-like toner as I can reach, then wash the remaining pieces in alcohol or warm water. With the motor removed you should be able to cycle the service station easily with your fingers.
Usually nothing is broken, it's just gummed up. =^..^=If you'd like a serious answer to your request:
1) demonstrate that you've read the manual
2) demonstrate that you made some attempt to fix it.
3) if you're going to ask about jams include the jam code.
4) if you're going to ask about an error code include the error code.
5) You are the person onsite. Only you can make observations.

Re: DesignJet 500 21:10 error
No, it was a new service station. I took apart the old one to see if there was anything broken, or jamming the cleaner (like a piece of the old belt), but it was clean and moved easily by hand, same with the new one. There was a little buildup on the scraper, but nothing to speak of. The spittoon is just about empty. The wheel spins easily. I was figuring it was the motor, but with the new one also? Thanks for your reply.Comment

Re: DesignJet 500 21:10 error
Probably not the motor. Just make sure the the service station is in the retracted position before attempting to start up the machine. The print head can hit the cleaner, preventing both from moving properly. =^..^=If you'd like a serious answer to your request:

Re: DesignJet 500 21:10 error
Went back and tried old service station again, making sure the flag was in the proper position, and tried removing the printheads. It still popped the 21:10 error and didn't ask for the printheads. The motor on the service station just buzzes when it's trying to move, but everything moves freely, and if you remove the motor the gears move very easily. Power supply issue? If that was the case, I would figure that the carrier wouldn't move, either, but it does. Going to try the firmware today, and we'll see what happens.Comment

Re: DesignJet 500 21:10 error
can you run the motor out of the service station, if it still buzzes, then you have an issue with control signal for motor, either power supply or electronic module, not sure were it comes from , been a while since working on HP plotters, oops there called wide format printers now. It is sometimes the motor but most of the time it is the driver ic/transistor for the motor.Comment

Good idea! Kicking myself for not thinking of that... old age.... yeah, we'll go with that one. I'm going back this morning, we'll see what happens. Thanks.Comment
