4900 Major Clogging

#1

Hello and apologies if this is a repeat post.

VLM was completely clogged but I was able to get partial success using a PC software doing an Initial Ink Charge using the instructions on 2manuals.com.
LC and LK are partially clogged as well.
We have tried everything else possible, including overnight Windex a few times, Powerful Cleaning dozens of times and nothing seems to work.
Coincidence or not, these 3 inks are the ones from Inkjet Mall.
What are we doing wrong, since so many have success with these inks?
Any ideas on how to proceed before I junk this machine?

Thanks in advance for any help,
Best regards,
Adhemar

Hi Adhemar~

I have moved your post to the appropriate topic: “Printer Maintenance for Pro 17” or wider"

After reviewing your order history, I see you bought the VLM cart and ink last Sept, LK in Oct, then LLK, Y + LC in Nov.
Did you prime cartridges to fill the exit channels with ink before installing refill carts into your printer?
Are the air vent plugs removed from all the refill carts?

Please let me know so I can help.
Warmly~ Dana :slight_smile:

Hi Dana,

Thanks for the prompt reply.
We didn’t install the VLM until late October and the Yellow is still in its original bottle.
The only cartridge working well from Cone is the LLK.
We did prime the cartridges as instructed and as shown on the video.
The air vent plugs have been removed also per instructions.

Any ideas?
Thanks,
JR

Thanks for the additional information. I apologize for not responding sooner, I’ve been tied up with workshops over the past two weeks and not on email as much as normal.

How often have you been agitating the ink carts since they were installed?
How often has the printer been used vs. how long has it sat unused?
What are the temperature and humidity levels in your printing environment?
When did you start having problems with these three channels not fully printing?
What happened before the channels stopped fully printing well- had the printer sat for a while, were carts refilled, etc…?

The refillable carts work very well, but a big difference between the refill carts and Epson carts is that the refill carts draw ink from the bottom, so if not regularly agitated, pigment will settle and thick ink from the bottom will be drawn into the ink lines, causing particle build up in the dampers to occur faster than normal. If this is the case, then dampers can’t be cleaned and need to be replaced. The dampers (“Ink Selector Unit”) costs about $195 from Compassmicro.com, here: http://compassmicro.com/parts_detail.cfm?ID=6812&form.mfg=Epson&form.printerstyle=Inkjet&form.printername=Stylus%20Pro%204900 (which is a lot less than throwing away the printer and buying a new one). Repair procedures can be found in the Epson field repair guide, which you can get online, one place is www.2manuals.com

Please let me know, thanks~ Dana

Thanks Dana,
We just can’t deal with this machine anymore, not worth the time and the effort.
We have 2 Canons that work flawlessly every single time so it’s only Canon for us from now on.
It will be a very satisfactory day when I personally throw this Epson in the dumpster.
All the best,
JR

Hi JR~

If you’d like, I can help you convert it to a Piezography printer to make use of the 7 good working channels. Otherwise, we may be interested in it as a testing machine, and could issue a UPS call tag if you don’t want want it anymore. I’d hate to see it go into the dumpster if it can be used for something!

Let me know, thanks~ Dana :slight_smile:

Hi Dana,
We would’t be interested in a UPS delivery as we’d have to crate the beast, I rather someone local came in pick it up.
We may be interested in a Piezography system.
What are the clogging issues with it and roughly how much will it cost?
Thanks again,
JR

Yes, I understand packing it up can be a project. I know someone in Chicago who may be interested in picking it up, and will check with them.

Piezography ink is pigment like ConeColor, and uses the same refillable carts, so we recommend regular agitation of carts and use of the printer to avoid settled pigment. We have several customers happily printing Piezography with their 4900 printers. If you haven’t seen Piezography prints before, I suggest you get a set of printed samples to see: http://shopping.netsuite.com/s.nl/c.362672/sc.15/category.42451/.f

With 7 good working channels, you can set it up for matte (non-gloss) Piezography printing, and we can modify curves for your custom ink shade placement. The cost will depend on the size ink bottles you get, but you can see carts, 700ml and 350ml bottle sets here for Special Edition K7 inks (we have five different ink tones, this is just one option): http://shopping.netsuite.com/s.nl/c.362672/sc.15/category.82555/.f You’ll want to look at the Matte only bottle sets.

Please let me know if you have further questions or there’s anything else I can help you with.
Warmly~ Dana :slight_smile:

Hi Dana,

I’m familiar with the Piezography system, we had an Epson 1280 using your inks way back when in the beginning of this system. It ran well and we still have prints here from that machine.
I’ll think about the conversion this weekend and I’ll let you know on Monday,
Thanks again,
JR

Great, the 1280 was one of the first Piezography printers like 14 years ago (yes, I’ve been working with Piezography since the very beginning).
Piezography has evolved quite a bit since the 1280-era, print quality (and printer quality) has improved over the years (though the 1280 made a beautiful print back in it’s day!).

Enjoy the weekend and let me know if there’s anything else I can help you with.
Warmly~ Dana :slight_smile:

Hey Dana,
We have sealed and unopened bottle of Yellow color kit for the 4900 (CCP-4900-220-Y-KIT), order SO30743956.
Any chance you can accept it back?
We are still debating on the conversion to Piezography.
Thanks again,
JR

Hi JR~

I checked with sales and as per our return policy, we only accept returns of unopened products within 15 days of receipt.

This is the wording of our return policy regarding unopened merchandise:
“InkjetMall will accept authorized returns on unopened merchandise for 15 days from receipt for a full refund on the merchandise only, less a 15% restocking fee. Returned merchandise must be in saleable condition in its original packaging. Authorized returns must be received within 15 days of an RMA being issued and will not be accepted after that.”

Please let me know if you have questions or there’s anything else I can help you with.

Warmly~ Dana :slight_smile:

Thanks Dana,

Please understand, we DO care deeply and bend over backwards to help our customers every day, but have clear return policies, and 3mo is a lot longer than 15 days.

Best regards~ Dana

Understood,
No problem at all.
