Good day. I have to clean my printer head EVERY hour. Then it prints fine. Until I leave it for an hour. So this leads to waste pad full and I have to purchase a key every time. Is there another way to go around this problem please? I cannot afford to buy a key every week.

You have to make 2 things
- clean parking station first - then inks will not dry on printhead;
- use high quality inks.

I took a gamble last week by buying a Epson Pro 4900 for less than $140 thinking if I could not get it going, I can at least take the remaining ink out of the cartridge and use it on my other printers.

The initial nozzle test was not so bad for a printer that was unused for about 1 year, I got six Nozzles firing at around 90% not bad, the next thing I did was the popular Windex treatment, I ran 4 sessions of Windex treatment on the printhead, first one lasted 1 hour, second one lasted 2 hours and third one lasted 4 hours and the last one lasted 8 hours, I got a fully soaked paper towel in my last two treatments, I ran a series of power clean on the non firing nozzles but the Green nozzle remain clogged.
At this stage I thought this program may be my last chance to rescue this printer. I bought the program at 6 pm today, I ran the CL1 clean on OR/GR channel and the green nozzle remain clogged, I then ran the CL2 clean on the same nozzles and the same result, at this point I thought maybe this printer is completely dead but I will give CL3 a shot, I went for dinner when CL3 clean was performed on the printer. I came back immediately printed the nozzle check I got the perfect Nozzle pattern on almost every single colour nozzle except Cyan which has a few bar missing, a quick CL1 clean on Cyan/Magenta fix that.
The next thing I did was to run a quick paper profile on this printer with X-rite software, I printed two test pattern page to calibrate the printer, then come the first real print on my Epson Stylus Pro 4900 it was absolutely brilliant, the best printer I have ever own and the IQ on one of the cheapest glossy media I could find was simply breath taking.

I have to say without this software my $140 purchase would probably end up in the rubbish dump.
I must say I was skeptical about the truthfulness of the success that other has with this software but with myself actually tried this software, I have no reservation but to recommend that anyone who has a clogged Epson Pro 4900 to give this program a shot it may just save your printer.

On the scale of 10 I would probably give it a 11 and it is more than just good!
