I have an Epson Stylus Color 400 printer. Inkjet, it would seem. I replaced the cartridges, and now it prints just fine in colour. But if I print in black, I get large gaps in the printout, and where it does print, there are many horizontal lines of unprinted space.
Windows XP. Printer some years old, bought for $5 at a yard sale. Initially didn’t print at all.
New ink cartridges and the print head cleaning utility solved the problem for colour printing. The machine still refused to print in black. Printer disconnected, stored in box in bedroom for five months.
New printer (HP Deskjet 840C) acquired for $0 because my father’s workplace was throwing it out. Drivers were not on hand. When connected to a Win 98 system, printed jibberish endlessly, and had paper loading problems. Internal inspection, padding of paper tray and connection to Win XP system solved the problem. Printer entered service with the handicap that it only draws paper when the tray is nearly full. This printer is, judging by the print quality and new refusal to print in blue, about to run out of ink. Online quote for a new ink cartridge: $87 (Staples Online)
Epson-brand printer reinspected this weekend with aim of putting it into service to replace the HP. Colour printing works perfectly. Printng in black gives gaps and horizontal lines.
I’ve run the head cleaning utility so many times that the ‘Almost Out of Black Ink’ light is blinking. (keep in mind this is a black ink cartridge which has printed nothing but the very short test pages that contain a few black and coloured parallel lines).
The printer case says “Disconnect input power before servicing.”
Research began yesterday. I’ve read through most of the relevant threads (searching on “print*” in thread titles in GQ) and learnt:
Epson printers are known for this problem.
Soaking the print heads in Isopropyl alcohol may help.
Among many other things.
I now plan to run the cleaning utility a few more times, and if that doesn’t work, to open the printer up and see if I can fix the problem.
So, here’s what I want to know:
- Have I missed something that would save me dismantling the device?
- If I have to take it apart, is there anything I should know before I do? What to look for, what not to do, etc.
Thanks ahead, wolfStu.
