T1200 MFP printer/scanner question

Re: T1200 MFP printer/scanner question

I've read about being able to replace with a regular flourescent.

I did that with the last one I did. Just have to make sure it's the correct tube (brightness) for proper color reproduction. I don't remember anymore the tube number.

Is this machine under a service contract? If so tell them to keep replacing parts until issue is solved or if they would like replace with another of the same model. After all it isn't you who is guessing at parts because of not being able to solve an issue. You can buy used working T1200 printers without the scanner & controller at low prices. Tell them that may actually be the best route and save them time and money in the long run. I have done it with copiers, it gets to a point you pull the machine and replace it with the same model. Keep old machine for parts. Fortunately not often because I take it personally and won't allow a machine to beat me. But once in a while you just have to give in. But no worries because I'll be the winner in the end... Stipping the parts off than throwing into dumpster real hard !!!

By the way have you had issues with the exp lamps not lasting, or maint messages & calibration. Have only worked on a few T1200 and both had exp lamp issues. Those exp lamp units aren't cheap $400-500. Fortunately I found a way around paying that ridiculous amount for basically a fluorescent tube lamp.

Haven't had any trouble with the scanner lamp (knock on wood) so far and we've had it for over 10 years now. I've read about being able to replace with a regular flourescent.

Sure wish it was under a service contract! No such luck.

Yes, buying a used T1200 is probably a good choice and it's the way I would go if it was my personal equipment. But since it belongs to the company I work for, they're a little reluctant to buy a used model for fear of getting into another problem unit. But I'm going to start looking to see what's out there in the used equipment area.

Thanks for the input!

Typically, printheads cause banding. Everytime I've seen banding, it's always been a faulty printhead. Check your printhead expiration dates on the heads themselves. Print the PQ Diagnostics from the menu and any colors that show banding, replace the corresponding printhead. As for the hooking up to another plotter........they may be right. I don't have a lot of experience with the designjet scanners. Doing a quick search on the HP site for the 4500 scanner series, I see the last software update for the 4500 was in 2014 for the 'A' and 'B' models and 2015 for the 'C' models. The software for the scanners is just re-shelled (skinned) version of Windows. Typically WindowsXP.

All the printheads have been replaced. It was the first thing they tried. This "banding" is more like ink not present and the lines are about 4-5" apart. I think I need to post a picture to clarify. Also, when you watch the paper advance, you can see the paper move just a 1/32" too far every 14-17 passes of the carriage. Most banding I've seen on other printers looks different from this. On this one, it's like the paper moves too far. Something you'd expect to see if there is a missing tooth on one of the gears. So more mechanical than ink supply type of problem.

*EDIT: I should add, when the "banding" happens, especially on a line drawing, you can tell the paper advances too far because the lines are out of alignment, rather than the ink missing.

I have a Designjet 800 that I'm thinking of hooking up to the scanner, just as an experiment, to see if it will print directly from the scanner to the printer. Nothing to lose at this point.

Thanks for the input!

We have a T1200 printer/scanner (4500mfp) that we use for both line drawings and printing graphics. It was bought as a set. The scanner is working very well but the printer is developing a banding problem that the HP techs can't seem to fix or even diagnose with any certainty. It leaves an empty space about every 17 carriage cycles. So far, they've replaced the encoder strip, the advance transmission and the star wheel motor. We're not certain we want to put much more money into this printer. They said the next item to replace would be the carriage itself but they're not sure that would solve the problem either. I can post a picture, if that would be helpful.

The question is how we can keep the scanner and put it together with a new printer and have the same good working relationship between the two. Presently, we can scan an image right to the printer, which is great. But I was told today by the HP repair tech and by our HP rep that the scanner will not be able to do that with the new HP printers. I was told the software on that scanner only matches up with the T1200 printer so you can't just plug the scanner into a different printer and scan directly to that printer like we do now. Our only option is to buy a new printer that has the scanner built right on to the printer.

Does anyone have some insight into this? Is it true that scanner will only work with the T1200 printer that it came with when we first bought it? Or is there a way to change the software on the scanner to make it work with a new HP printer?

He said the only other option is to scan to the server, then send that file to the printer from your desktop computer (via the server). We could do that of course, but it's just an extra step that costs more time.

Thanks for any help.
