If you think that the head replacement procedure is to difficult, you should let something do it for you. The procedure will not be easier with an other documentation.
Roland tech
It is true, you need to be sent to Roland as an employee of a dealer. Becoming a dealer is expensive, demo equipment, parts, supplies etc. Many dealers are having to lay of techs recently so look for independant tech, they usually charge less. All else fails, get a tech manual and read up on your printer. The folks we see getting in trouble are the one who just start taking things apart (usually with the power still on) and fry boards.
I have a list of techs if anyone needs one, not everywhere but a pretty good selection. And if you need parts check out our site at www.solventinkjet.com
We also supply free tech manuals(I have most, not all) when you buy your parts from us.
I am a technician at a personalization company and I do all the repairs on our Rolands myself. I've had no training on Rolands, but I do have an associate degree in electrical technology and worked at a plastic container factory for 4 years before I got my current job about a year ago. That being said Ive replaced just about everything you can on a Roland and there really not that difficult. The hardest part is having the troubleshooting skills to figure whats broken from the symptoms. I've recently been thinking about trying to start my own repair business but I am worried I wouldn't have enough clients. How many of you would hire a non-certified tech to work on your equipment even if the price was cheaper?
