Today a HP Latex 700W was displaying a 150L maintenance warning. The impinging module, service station, slider rods, encoder strip and cooling vents were cleaned. Everything is looking good!

A new customer has a Mimaki UCJV300 that needs a new printhead because of delamination. The customer supplied an oem printhead and I installed it. The installation on the new printhead went as planned. When test cutting the cuts and spot gloss was off. After checking out the machine further it was noticed that the main UCJV300 body was not square on the stand, some pinch wheels were not all the way on the grit wheels, the rear media holders were off to one side causing the slack when retracting to be higher on one side than the other, causing skewing. Likely this was the cause of the delamination when the media was jamming into the head. The cuts and spot gloss are right on now and the customer is very happy.

Worked on two HP Designjet Z6200 large format printers located in Twenty Nine Palms, CA, both of them needed y-axis belts. One of the HP Z6200 was leaking ink into the carriage crane and onto prints and other stuff. A couple of seals were replaced, the inktubes system was pressure tested. A huge mess was cleaned upped. Both HP Z6200 were oiled, and calibrated. Prints looked good.

Work on a HP Latex 700W today, customer says that they are having problems loading media and getting media jams. Inspection found the profiles needed adjustment, the machine needs a cleaning and lubrication. The y-axis belt is wearing prematurely because there was some debris in the pulley, the cleaning took care of that.
