Hey all,
Thought we might return to the topic of purge units.
I've reassembled the purge unit for my ip5200, with the repairs I had made. It would be a little difficult to describe these repairs without pictures (which I have), so I'll just say that it involved, a hairdrier, GOOP, tape, a penny, and a dime (Canadian currency).
It appears the repaired carousel-cylinder set inside the housing is holding. However, the plastic wood I was temporarily using to lock the drive gear on its axel, failed immediately, as has 4 different types of contact cements, which were lying around the house. I'm going hunting this weekend for a replacement gear or an appropriate epoxy.
In one direction the gears control the movements of the various parts. In the other, the gears rotate only the carousel sets. This motion has the most tension/friction, and was initially causing the carousel-cylinder to come apart . This makes sense, as it is this direction of motion which "milks" the purge tubes, and drains the purge pads. It is the friction in this motion which keeps stripping the gear from the axel.
So at this time, I've removed the drive gear and axel, and am just performing tests.
Since the printer never even completed its initial setup, the waste ink pads located under the printer chassis are completely clean, with the exception of 2 or 3 drops of ink. After cleaning the printhead (which took a while, but yielding a lot of ink), and reading the posts about checking the suction action of the purge unit, I got to thinking that maybe the purge pads had clogged with dried ink, since they had never been "sucked" clean, and had been sitting for a looong time.
Using windex on the pads, I soaked up the ink in papertowels, which also yielded a lot of ink. Eventually, by turning the gears, I was able to get ink to start flowing through the purge tubes. The pads have now turned from black to white.
Note: If you do this in your family room, and realize you've dripped ink on your beige carpet, Isopropyl will help clean it up before your girlfriend notices.
Maybe this should also be considered when diagnosing printing issues when a printer has been sitting for a long time, or experienced a purge unit failure.
Anyway... hopefully I'll be able to fix the drive gear this weekend, and providing that I haven't wrecked my printhead, maybe I'll have some positive results.
