Happy to hear it!

Well done!

Chinese ink cartridges can cause this problem also. If you are using them, install HP ink cartridges. Otherwise, replace the ISS. www.lpscomputer.com/collections/designjet-500-800-parts-page/products/c7769-60373-hp-designjet-500-800-ink-supply-station

Glad we could help!

Hi. The Error code 22:10 indicates a communications problem between the Ink Supply Station and the Electronics Module. Replacing the Ink Supply Station usually fixes the problem, however, the data cable between the small interconnect board and the Electronics module could also be the problem. Very rarely, the interconnect board is the problem. The parts can be found at: www.lpscomputer.com/collections/designjet-500-800-parts-page

Printheads or ink cartridges? I've not heard of poor printhead connection causing 22:10.

Sorry, I did a few typo. I had corrected it now. Printheads are linked to ink supply station (ISS). As you mentioned the Ink Supply Station communicate to the Printhead carriage unit. Cleaning the contacts on two printhead did the work for us.

I've try a lot of other cartridges, all of them are new, it didn't help.

It is likely your ink supply station is faulty.

+Bob Wert thanks, i think so too

Hello. Most of the time when you get an error 22:10, replacing the ink supply station fixes the problem. When it doesn't fix it, the problem is most likely the interconnect cable. The cable is a known problem and causes intermittent 21:10 and 22:10 errors. The cable plugs into the interconnect board behind the display and goes through the center of the plotter and plugs into the electronics module on the other end. When you replace it, tape the new cable onto the end of the old cable to pull it through the machine when the old one is being pulled out. There are 2 sizes of the cable. One for the 24" print width plotter and one for the 42". The parts can be ordered from: www.lpscomputer.com/collections/designjet-500-800-parts-page/products/c7769-60298-designjet-500-800-interconnect-cable OR www.lpscomputer.com/collections/designjet-500-800-parts-page/products/c7770-60267-designjet-500-800-interconnect-ribbon-cable

Are you using new (not refilled) HP ink or 3rd party ink? I recommend using HP ink just because of the large number of problems I have seen caused by refilled or 3rd party ink.

Hello. The ink cartridges share some electrical signals. If one of the cartridges is having a problem, it can effect the others. It would be useful to have a set of near empty cartridges to swap out one at a time to determine which ink cartridge is failing or a new set of ink cartridges. We have some used ink cartridges that are at least half full that we can sell you for $13 each if you are interested. To order, please call 800-959-1575 or go to www.lpscomputer.com/collections/designjet-500-800-parts-page

Hi Erik, There are a couple possible causes for error 79:04. Please email sales@lpscomputer.com for further discussion.

You're welcome!

Hello. The 2 types of ISS are interchangeable. The ink slots are identical - same ink. The cartridges cannot dry out under normal conditions (not out in the sun for a couple of years). There is a sensing issue with the ISS or the data cable connecting the interconnect board with the electronics module. The interconnect board is the small board the ISS plugs into. You might want to replace both. www.lpscomputer.com/collections/designjet-500-800-parts-page?page=3. The ink cartridges share some signals, so 1 defective cartridge may make them all look bad. Remove all the ink and cycle the power. When the plotter asks for the cartridges to be installed, put them in one at a time. If the plotter accepts it, take it back out and go the the next one. Try to find a bad cartridge. If you are using aftermarket ink, replace the ink with HP OEM ink. www.lpscomputer.com/collections/hp-designjet-ink-printheads

The ink supply stations are interchangeable and the same ink goes into both. The ink cartridges contain plastic bags with the ink. It is not possible for them to dry out without leaking. The cartridges share some basic signals, so if one is not passing along something like the 5VDC, the cartridges down stream will show bad. Try a fresh set of ink cartridges. It is also possible the ISS is bad or that you did not plug both cable bundles back into the interconnect board.

The LPS video on Designjet 500/800 belt replacement shows the removal and replacement of the carriage. See: kzfaq.info/get/bejne/es6hZKxzss-maGg.html

Hello Ben, Please refer to this blog post: www.lpscomputer.com/blogs/news/78686913-designjet-500-800-error-86-01-after-belt-replacement

Ah, so I think I found the problem. You know the pistons that push up into the ink cartridge to determine how much ink is left? The spring popped off the mechanism for the cyan one so it doesn't push up. Would that throw the 22:10 error?

Well, we put in a Ink Supply Station from a backup plotter, and after going through the 11-min printhead alignment, it threw the 22:10 error again. Does that mean it's a problem with the cheap chinese ink we have? Cause it wasn't throwing the error in the other plotter. Also, would a problem with the ink tubes throw the 22:10 error? The ink connections seems to be pretty gunked up at the cartridge end (again, cheap chinese ink), but it's printing fine.

Ideally, you always want to use HP OEM ink cartridges, if nothing else, for reliability. Pistons failing to pressurize the ink cartridges can cause 22:10. However, air in the ink tubes can also cause the machine to believe it's failing to pressurize the ink cartridges, since the air compresses, whereas ink does not. If you need to get air out of the lines, I suggest you purchase our universal priming tool.

If you put the same one back in, it shouldn't even ask. Because the machine doesn't think anything has been changed.

Okay that makes sense. Thanks!

There is a small chance your issue is caused by a faulty interconnect PCA (C7769-60042) or interconnect cable (C7770-60267), but the best bet is to start with the ISS.

Bob, I have purchased the replacement ISS from LPS. Followed your video and upon initializing and rebooting it came up with the same icons as before. You mentioned a faulty PCA and Interconnect cables in your response do I install one before the other ? Please advise as it appears I may have just chucked $90.00 bucks out the window. Thank you for your time.

You can start with the interconnect PCA, since it's simpler to replace. In the event you end up with purchased parts you don't need, you can always return them.

Thank you, I will give that a try.

If you are using aftermarket inks, try installing HP brand cartridges only. If that doesn't solve the issue, use the priming tool to purge the ink tube system. www.lpscomputer.com/products/designjet-ink-tube-priming-tool

System Error: 05:10

System Error: 05:10

Did you buy the service station from LPS? Make sure to use the correct screws for mounting the service station. If you use the cover screws (which will fit), the service station wiper tray will impact them, because they're slightly longer than the service station mounting screws.

Error 21:10 indicates a service station problem. Sometimes the SS gets roughed up in shipping. Contact us and we will replace the SS. 800-959-1575

Chinese ink cartridges can cause this problem also. If you are using them, install HP ink cartridges.

This may be a bad power supply. www.lpscomputer.com/collections/designjet-500-800-parts-page/products/c7769-60145-r-c7769-60387-r-designjet-500-800-power-supply

Hello. Occasionally the 22:10 error is caused by a faulty data cable. The cable connects the small interconnect board (board the ISS and service station connect to) and the electronics module. It is the broad connector at the back edge of the interconnect board and runs through the plotter to the left end. You can order the cable at: www.lpscomputer.com/collections/designjet-500-800-parts-page/products/c7770-60267-designjet-500-800-interconnect-ribbon-cable for the 42" plotter or www.lpscomputer.com/collections/designjet-500-800-parts-page/products/c7769-60298-designjet-500-800-interconnect-cable for the 24" plotter.

Bob Wert thanks Bob. I did the ISS test operation and the result was positive. Could the same be the cable?

The cable passes all the signals from the ISS, Service Station and display. Missing or weak signals will be misinterpreted by the electronics module as a malfunction in the device associated with that signal. The answer is yes.

Hi Bob. As suggested by you I replaced the cable but unfortunately error 22.10 remains. I'm going crazy. Do you have any other suggestions? Thanks

Hello again. The only parts left in the food chain is the small interconnect board that the ISS plugs into and the electronics module. Start with the interconnect board.

Hello Daniel, To reset the usage counter, start the machine up normally and enter the Set-up menu (bottom option on the main screen). Then press the "up-key" and "enter" at the same time. This will bring you to the "Service tools" menu. You should see three options. Select "Service utilities. Then scroll down to "EEROM Setup options." Now you will see an option for "Reset usage counter." In this submenu, you can pick whichever component that needs its usage counter reset. I suggest you start by resetting the spittoon counter and the service station counter. Bob

Thanks! That seems to have cleared it up.

Not sure what you mean by not aligning. Print heads? Could be a worn out belt not positioning the carriage accurately or paper that "bleeds" so much that the line sensor cannot accurately locate edges.

If it's asking for setup printheads, you can tell the machine you've installed them. The setup printheads don't have any electronics on them, so the machine doesn't actually know if they're installed or not.

Bob Wert plotter is hp 500 plus, le testine sono gia installate ma dopo aver risolto il problema dell’errore 22:10 , il plotter mi chiede di installare di configurazione, ma nel plotter gia ci sono le normali testine. grazie , attendo un tuo consiglio

the plotter hangs up asking me for the configuration heads, how can I say that you can continue working? what is the path on the menu to solve this plotter request?

Hello. I am assuming you have a Designjet 500 or 800. An error 79:04 is a very general error having to do with firmware. The plotter is confused. This could be caused by a bad file from the computer or an internal hardware problem in the plotter. The first thing to do is try printing another file. If it still fails, disconnect the plotter from the computer and do an internal plot like a print head alignment. If the error goes away, the problem is with the computer. Download and re-install the newest printer driver from HP. If the problem is still present when disconnected from the computer, the problem is in the plotter. Supplies can cause this problem. If you have them available, replace all the ink cartridges (HP OEM only) and print heads. If the problem is still present, replace the formatter - see kzfaq.info/get/bejne/jbaClr2VvNS-YWg.html (designjet 800). Still not working? Replace the electronics module. www.lpscomputer.com/collections/designjet-500-800-parts-page?page=2

Thank you
