Tech Help — Designjet Z2100

Question: "Hi, I recently did my second belt replacement on my T1100 (both belts from LPS as they appear to be the only ones with the guide ribs). The first time everything went well. This time, the machine keeps insisting on a printhead replacement. I've tried the printhead recovery kit (and changed printheads), and ink readily flows through the tubing into the printhead carousel. But the system keeps failing the first printhead, telling me to reseat/replace it. I do this, it moves to the service station, and fails again. Is there anything else I could have mis-reconnected? the cable and... Read more →

If your Designjet printer is showing error 58:10 "Color sensor ESP (spectrophotometer) if the printer is not working well," or a related 58:xx error, the problem may be mechanical. Historically, we've assumed the issue must be with the color sensor itself, or with the carriage PCA, but we've recently discovered a fairly common failure, and believe it or not --it's related to the service station. If the ESP lens shutter is unable to open, error 58:10 will appear. The mechanical actuator that slides the shutter open is located on the service station wiper tray. If this small actuator breaks, the... Read more →

"Printhead replacement incomplete" after "preparing print system" on a T610, T620, T770, T790, T1100, T1120, T1200, T1300, T2300, Z2100, Z3100, Z3200, Z5200 or Z5400? This is usually not enough ink reaching the printheads: a non-HP cartridge, a cartridge below 40% full, or air in the ink tubes. Install HP cartridges above 40% full and purge each ink line with the priming tool. If the tube system is compromised, the seal upgrade kit is the easier and cheaper fix.

This problem occurs in the following HP Designjet models: T610, T620, T770, T790, T1100, T1120, T1200, T1300, T2300, Z2100, Z3100, Z3200, Z5200, Z5400.  If your printer is rejecting HP 70 printheads or HP 72 printheads, or if the printheads seem generally unreliable, there's a good chance there's nothing wrong with the printheads themselves. Often the contacts on the trailing cable corrode, and fail to send a consistent signal to and from the printheads. If you're on your second or third replacement printhead, and about ready to put some creatively-placed holes in the printer, power the machine off, and check the... Read more →

Error 02.1:10 on a Designjet T1100 or T610 This is a printhead voltage fault on the carriage PCA. First try a different printhead in case one is pulling the carriage PCA down. If the error stays, replace the carriage (it comes with the PCA installed), and consider replacing the trailing cable at the same time. Parts you may need: T610, T1100 carriage with PCA Q6687-67009 | 44" trailing cable Q6659-60177 | 24" trailing cable Q5669-60681 "I am asking for your valuable help.
