DesignJet T2500 Repair Blackpool, Lancashire
Nice little journey to the seaside last week, to carry out a DesignJet T2500 repair in Blackpool, Lancashire. Whatever you say, going to Blackpool for any reason, always evokes great memories of day trips to the illuminations with my family when I was a kid. I even spotted the tower before anyone else. OK I was on my own, but it still counts.
Back to the problem, the DesignJet T2500 was asking for the printhead to be re-seated every time it completed a print. – this is a serious error. Not only is it frustrating and time consuming, but every time the printhead is re-seated, the machine runs through its “Install Printhead Routine” which is very expensive in wasted ink.
Repair Procedure
This was tricky call, as I wasn’t the first engineer to attend for this problem. A previous engineer, had replaced the primer pumps for both Ink Supply Stations, which, obviously hadn’t resolved the issue.
The first thing to do was upgrade the FirmWare. This is necessary for every call. Never try to fix an error on a machine without carrying out this step, if possible. If the machine won’t boot it may be difficult, but should be done as soon as possible.
Looking at the error logically, the printhead was fully working, but dropping “off the radar” after every print. This suggested to me that the problem was an electrical and not a physical problem, I.e. it had nothing to do with the ink flow into the printhead reservoirs.
That being established, it was either of two parts that were causing the problem.
Having done the “Phone Triage” correctly, I had brought both parts with me. From here it was just a matter of discussing the action plan with the customer and getting the “green light” to proceed.
Logically, you only replace one part at a time, and always start with the easiest one.
Having replaced the one of the suspected faulty parts, the machine was rebooted. As expected, the DesignJet Booted up and after initialising the ink system came up to ready. It didn’t go through the printhead installation process.
At this stage things were looking positive.
Calibration & Testing
Whenever any part is replaced on a DesignJet, there are usually several calibrations that need to be undertaken. In this case the Paper Advance Calibration and the Printhead Alignment were required. Also, the Drop Detect Sensor was calibrated – These were carried out successfully.
Several more tests were completed: Print Quality Diagnostic, Advanced Nozzle Print Test and a couple of the internal prints were done. No errors were reported.
Over 20 years’ experience in the DesignJet Repair Sector has taught, always reboot the machine once its fixed. This was carried out successfully. The machine was then given to the customer for live testing.
Several printouts were sent to the DesignJet, before it was rebooted again, and several more customer prints were carried out.
Sign Off
At this stage the DesignJet Repair Blackpool has been successfully completed. It took a while and needed extensive testing. This was mainly due to the nature of the problem, being intermittent. Its easier and cheaper to spend an extra 30 minutes on site than to have to revisit.
The key to any DesignJet repair, is to take your time, be methodical, and carry out all required calibrations and tests. This ensures a happy working machine, a happy customer, and a happy engineer.
