How to Change the Ink Pads in an Epson DX7450

I have just repaired my DX7450 (faulty power supply) and I thought ''whilst the printer is dismantled, I'll just check out the waste ink pads''. The problem is, I cannot see any way to access the waste ink pads (other than see the waste ink pipe through the tiny rear access panel - which is no use for anything really). To get to the ink pads in the bottom of the INNER plastic casing seems to require complete disassembly of the printer mechanism. This is not practicable without special re-assembly tools/jigs I think. Does this mean that the DX7450 (and similar models) is junk once the waste ink pads protection counter reaches its limit? Or am I missing something? No-one seems to have a copy of the service manual - for free or for sale.

    Hi Jacklee - yes I can reset the counter, but than I would have a printer with a waste system full of ink - which I don't want. No-one has yet answered the question of how you replace waste ink pads (or a waste ink tank) that is not accessible unless you dismantle the basic mechanical framework of the printer that cannot be re-assembled without jigs etc.

Hi,

Whilst I don't have the service manual available I do have a suggestion regarding a way to keep the printer from flooding with waste ink.

You've probably already noticed a number of modifications for Epson printers like the R300, etc... where the waste ink tube is redirected to an external tank. This is something that the DX7450 can also be modified to do and the key thing is that aside from a small amount of waste ink dumping to the left side of the printer you'd be stopping any further ink from being dumped to the pads.

This would allow the existing waste ink to evaporate the water content slowly over time and leave the pads relatively untouched while you could simply empty the external tank whenever it was full. Bottom line, this approach would allow you to forget about the pads without have to change them.


Ok, that aside I have a question for you in that I am trying to locate a utility suitable for resetting the waste ink counter and so far haven't found anything... Do you have a utility that will enable this? If so could you let me know if you're in a position to share as I really could use it.

Hope that helps and hope you'll be able to respond shortly.

Martin

SOURCE: How to Change the Waste Ink Pads in an Epson Stylus DX7450

Hello,
Even if you had the manual there would be no mention as to how to replace the waste ink pads! This is a common problem to all ink-jet printers. The best way to clean it is to just get the carriage out of the way by pulling the power while it is initializing and wipe the pad with a flat head screwdriver to remove the built-up black ink. The black ink is organic material & will build up as the color inks are dyes and will not build up!
Use warm water on a paper towel to clean up any messes made.

How do I reset the sensor after a waste pad error message for an Epson 7000? The pad is not full and I need to reset so I can print.


Hi


Normally your remedy is to replace the "Waste Ink Pad/Pads" with a new one/ones and then reset the "Internal Waste Ink Pad Counter". The waste ink pads are normally housed in a black plastic box. They are located in the bottom of the printer, towards the front, just under where the paper starts to exit. You would have to remove the "Top Cover Assembly" to be able to get to the screw or screws that hold that assembly in place. If you cannot figure out how to remove the waste ink pad holder assembly [plastic box], you may need a service manual, for the removal procedure.


Also Replace the following parts and reset the counters as described below:
- Waste Ink Pads
- F Box
- Pump Assembly
- Cap Assembly
- Cleaner, Head
- From Maintenance Mode 2 enter the Counter Init. Menu and initialize the Waste Ink counter and Cleaning counter.

Also check the end article at this given link for the resolution of the problem:-

Epson DX7450 won't recognise compatible cartridges


This is a common problem and is caused by faulty or missing chips onthe compatible cartridges. You will need to get them replaced otherwise the printer will not operate. Contact the vendor where you bought them from and ask for repalcements or a refund.

EPSON PRINTERS how to replace inks in epson DX 7450


You must surely have sorted this one out by now Doris! However, if you haven't, how to change print cartridges on a DX7450 is very clearly explained in the user handbook (on the CD that came with your printer). Insert the CD and select "Custom Install" then "Users Guide". Once its installed, double click the new Epson Icon on your screen and selct "Printing" then "Replacing Ink Cartridges". If you don't have a CD, download the User's Guide from the Epson website at http://www.epson.com - just choose your locale, then select Get Drivers and Support - Printers.
