Epson Stylus 740: still clogged after solvent...

[I posted this to the 'main' forum before...probably the wrong place...so here it is in the Inkjets...]

Hi... I bought the special solvent here for my inkjet and tried it out both on the park-pad and with the more serious inject thru ports method and neither worked. I still have clogged heads. The test print-out gives randomly clogged markings, however---if that's relevant. Seems a bit odd to me that the clogging changes.

Also, I finally got low ink readings after my dozens of clean-pages and I replaced the carts with new ones (not refills, Amazon brand). They worked fine at first! --But clogged up in a day or so.

Can you take carts on and off to do things like the syringe cleaning---I'm guessing that you can but who knows maybe new carts shouldn't be removed then reinstalled.

I found the French translated dismantling website that walks you thru taking apart the heads for a direct manual clean. That seems like my next step. But I wanted to check in here first! Any advice?
"Can you take carts on and off to do things like the syringe cleaning---I'm guessing that you can but who knows maybe new carts shouldn't be removed then reinstalled."

You can do that a few times. Keep in mind that generic inks are not made to any real standards. So the ink can often create more clogs.

You might want to remove the ink cartridges and flush the heads again. Reinstall the ink cartridges and run a few cleaning cycles. You need to run the cleaning cycles to reprime the print head with ink.

You should never remove the print head. It is completely unnecessary and breaks the factory adjustments. If you need to soak the print head you can simply place a pool of the solution onto the cap assembly and slide the carriage back over the cap assembly and let it soak that way.

**Bummer...

**I've removed the carts a couple times now and flushed a couple times. No luck. I can print---the results are just lame---the black is real bad.

**So that whole French site is a bad idea?

**Hmmm, "cap assembly"---what's that? The only thing that the carriages slides over, that I can tell, is a sponge area at the right, otherwise it's just a long rail. I thought the sponge area was called something like the park-station. ?? Further enlightment requested! : )

Check to see whether the pump\\cap assembly is working properly. Put some liquid on the cap assembly (pad) and run 1 cleaning cycle. The liquid should have been sucked down through the cap assembly. If not, this is most likely your problem. Also, with this model, every time you remove a cartridge, it resets the ink counter so that any replacement cartridge (new or partially used) is determined by the printer to be full. If you remove\\replace a cartridge the printer will run out of ink before the ink out light comes on.
Hope this helps.
