I'm hoping someone could give me a little input on our problem we're having with our Seiko 64s. We decided to clean the heck out of the machine one day and due to lack of experience and knowledge we cleaned the heads the wrong way. Instead of raising the carriage properly we brought it all the way over to the right and wiped the heads with a lint free towel. After we were done with this, the light cyan and light magenta print heads started printing real bad. The calibration test looked like smeared lines on the light cyan and light magenta. We bought an alignment jig and did a real thorough alignment but that didn't help. We messed with the voltages and that didn't help. I just wonder if there's something else we should try before spending $2000 in new heads. Any suggestions or input would be greatly appreciated. I have scans of the calibration test to see what heads are doing if that would help. Thanks!
firstly, perform a "cap-fill", by switching the printer off overnight, and letting the heads soak in the fluid it floods the caps with. then re-power and perform a strong clean.
if that doesn't help, purhcase a "cleaning sheet" which allows you to park the carriage on the fluid-soaked sheet overnight to, again allow the crap on the heads to re-liquidfy and hopefully disperse. there should be instructions with the sheet, so just follow these.
I have just read your info with dismay, the Seiko heads should never be touched, not even with a lint free cloth, although you did not mention if you used some solution as well.
I am hoping you have not, but the chances are you have scratched the heads, follow Nigel Mansells instructions, check the caps and dampers and I cross my fingers for you.
We performed many cap fills, soaked the heads, changed out the magenta and cyan with the light magenta and light cyan and they are firing fine. All general service parts and maintenance has been recently replaced and performed on the machine. We did a head alignment with the jig tool, performed numerous calibration tests but the lt magenta and lt cyan still wont print good and the bi directionals are way off now. I'm kind of fearing a main board issue????? We were doing fine printing in 4 color but now thats not even cutting it.
so the heads are printing fine in different head slots. did you put the "good" heads into the "bad" slots, and if so did they print OK or not?
If not, then yes a board of sorts, be it carriage or main (probably carriage), or even the large white cable that connects the two.
Also check the dampers, as a faulty one can stop heads printing as they do not keep the correct pressure to allow ink to flow, therefore no print!
Bi-di's are easy to rectify, if not a little time consuming, but remember everything's aligned to the Black head, so never remove all the heads at the same time, as this will leave you no datum to work from.
Your Diagnostics, internal memory has gone down the pan, I have seen this on two or three machines.
No matter what you do, the BiDi settings cannot be adjusted and are always way off. Check this by adjusting LC and LM and reading them after...............
The remedy is simple, but a little time consuming.
1. take your cap, wiper position and head voltage, write them down, also print off your system settings
2. reset your nvram and settings, I think nvram is enough, if I remember correctly
3. you will loose all data, I repeat you will lose data, profile etc
4. you will have to enter all settings again, L/R head pos, I-Pos etc
5. Cap position is very important, if not set you will get an error, you cannot set cap position to 0, it has to be +/-
6. Continue along this path.
7. I AM SURE THIS IS THE SOLUTION, BE AWARE, I AM ONLY RESPOONSING TO THE DATA YOU HAVE POSTED.
