Digital BW, The Print

Dear Epson Printer technicans,

I don't want to beat a dying horse here and I will be dealing with this myself for a few days, 
But:

I just took off the parking pad assembly and checked all the lines - they appear 
unobstructed. It seems that at least one pad is worn down a bit, but I should be able to 
order the pads without replacing the whole assembly just to cover myself.

My question, to anyone out there, is - is this "PUMP" that brings the ink into the heads an 
actual PUMP that can wear out like any other PUMP ? Or, is it just the physical location of 
all these waste hoses going to the waste pads? If it is an actual PUMP this could very well 
be my lack of suction from the carts to the heads. And I would think they would instruct 
you to evaluate this first.  If it is not an actual PUMP then I won't 
bother replacing it.

This manual tells me nothing about the actual function and construction of this "pump". 
And, in typical Epson fashon, they just direct  you to replace the whole - pump, pad, 
parking pad, hose, assembly, etc. How rinky dink can you get. I can see why the Epson 
techs just replace everything and hope for the best, that is what their manual tells them to 
do. Repace this section or that section and let the customer pay for it.

I'll disappear for a few days and come back with a better attitude. I have really appreciated 
all the constructive information. 

John
