It sounds like you're trying to force the printer to clean the printhead and only ever partially resolving it before it clogs up again.
Ok... first you need to do is get a decent cleaning solution that can help de-clog the printhead. Usually Windex (the ammoniated version) is a good option but you might want to get some from your ink supplier.
Cleaning cartridges may be worth considerinb BUT I only ever use these are a passive cleaning system, not as active "clean NOW! dagnabit
" impatient approaches.
Right, anyway... process is this.
- Leave your existing cartridges in
- Find a piece of paper kitchen towel or if possible a lint free piece of cloth and soak it in the cleaning solution. Fold into a 2mm or so thick pad.
- Move the printhead off the parking pad and out of the way to the left. (usually by starting the printer, waiting for the head to move and then pulling the power cord so you can freely move the printhead).
- Place the pad of solution soaked kitchen towel and then move the printhead back to sit over this in the parking pad.
- Then go make a cup of tea/coffee, do the ironing, or whatever but leave it alone for at least overnight.
- Remove the kitchen towel pad and replace with a fresh one
- Leave for a further 12 hours
- Remove the pad and turn the printer back on
- Run a SINGLE cleaning cycle and then a nozzle check
- Let the printer sit for an hour
- Try using the printer as normal.
What this approach does is allows the cleaning solution to slowly break down the clog by whicking up into the printhead nozzles and over time turn the hard pigment into a solution again. This requires time so patience is an absolutely essential ingredient.
A few things to note...
- Obviously don't try to force a thick wad of paper towel under the printhead.. a single fold should be enough
- DO NOT use the towel to scrape back and forth across the printhead as this will damage the printhead (it is incredibly sensitive and paper towel is more abrasive than you may realise!)
- The cleaning solution is not just some off the shelf oven cleaner... If in doubt use distilled water and add more time to the process
- If you're using cleaning cartridges do not use them to force clogs out... Instead allow the solution in them to work on the clog from above in the same way as the pad of solution in the parking pad will work on the clog from below.
Hope this works for you and try to adopt more pro-active measures to reduce the likelihood of clogging ie:
- move out of particularly hot/warm rooms
- move away from radiators
- use the printer regularly (don't leave it idle)
The last one is the kicker... It's a lot like having a dog... They're happier if they're kept exercised so don't save the printer for special photos or whatever, try to use it for the odd graphic, letter too.
Good luck :)
