I was first skeptical when the tech walked in due to the fact that this is our first dealing with Kensington Office Machines. The tech dismantled my HP Designjet Z6100 Printer, replace the parts, cleaned the unit and reassembled the unit. My colleague and I were expecting the usual beep followed by the error codes when the unit was turned on but the unit did not beep and printer was ready. Our HP Designjet works fine now.
I could not recommend their services highly enough. Thank You!
