This is a great post. Could name it as "The story of a DX7 (short) life". Those "curls" in test print and some light - or bad ink overspray occurs on DX7 print heads when they are close to the end of service life. Those print heads print extremely good but they do not last. After 3 of those (the...

Thank you very much for your detailed reply! As I 've said in other comment, those flexible black tubes, replaced with new, some years ago when I stopped using white and metallic ink. (The MAX 2 white ink that replaced MAX was a disaster..!). It was solid hard chalk down at the "U" shape of ink...

Before last printhead change, choke valve tubes replaced with OEM new tubes, (the white line was like solid chalk..!). After that, no white or metallic ink used since then. System tubes was cleared with Pump up menu and cleaning cartridges. Head replacement took place with clean, empty ink...

This is the first I check after captop replacement. Some cleaning liquid on rubber gasket gives clean and better seal. Thank you.

Thank you for your detailed reply. I have the VS (from new) for about 12 years. In those years I have changed more than 36 captops. I replace them before they need replacing (about 3-4 per year). I have serviced this machine many times those years to keep it in top shape. In those years I have...

Captop is replaced the same day with new dampers. OEM part too. Before cleaning I applied cleaning solution for better sealing. Head is in low position. Flush position is also adjusted to eliminate any factor.

Yes, dampers are filled and there is no air in the lines. Checked many times. Is there any case that the printhead can block the ink flow AFTER choke clean? Printhead is in perfect optical condition, never ever had head crash, no delamination.

Thank you for your quick reply. I' ve lubricated the dampers o-rings and print head manifold "nipples" with cleaning fluid to avoid any force on thema and to ensure tight sealing. As I said before, the missing channels occurred after Choke Clean. Not right after damper change.

Hello, and I hope you are all well. This post has the meaning to collect some ideas because I run out of them. After 3 years of not intense but gentle usage of the 3rd DX7 printhead replacement of my VS-640 (Other 2 printheads replaced for the same reason: Light Cyan deflecting / misting) I had...

If you think, cut and then print is better (if you don't laminate). This is because the rollers don't press the freshly print media, and there are no marks.

"S" Logo is clearly upside down.

Thank you for your reply. FJ-540 scan motor is not compatible with SC-500. Compatible printers are CJ-500 / FJ-400 / FJ-500 / FJ-600.

Hello, I know that a SC-500 is now a dinosaur. :) Maybe mine is the only one that survived as sold, and I still use it mostly for cut only. But after all those years of service, the scan motor died. So, I am in search for a (new) motor, original part. Does anybody knows if I can still find one...

Did you try encoder check from service menu?

Hello, here is a strange issue that I can not cure: What would be the cause of air in the white ink line (has cleaning fluid for some months) moving away (goes up) from the damper? Even after choke cleaning, ink flows out the opposite way. Also there's a lot of air bubbles in the ink line and...

Hi from Greece..! If I rememeber well you had a SC-500 like mine (?) Now you have VS as I do. How are you?

The point is that I never had a captop with the wire. On the other hand, the captop with the wire must be somehow different from the original type.

Hello, all those (many) wears I use original Roland parts. Roland made an update a long time ago to capping sponges (called also "filters") to the original capping station for DX2 print head printers like SC-500 I own. Mimaki made an improvement to the same part adding a wire mesh to prevent...

I think it is much better to replace it with a good desktop, made to work for years, easy to upgrade. Most important is to have more than enough memory and one HD for work backups.
