Okay after speaking to them I now have the proper story, all of which I understand.
The printer is not a disc printer but a domestic photoprinter with disc printing abilities, this is stated on the box. If the tray stops working within waranty and you have used it for domestic purposes the try will be replaced for free. Now the old tray with the clear platic strip at the front is the one that caused the problems, which is the one I have and is no longer supplied, as the thin clear plastic strip at the front could warp. The new tray, the one in your picture, does not wear out in the same way as the old one and thus would last longer. The lady I spoke to explained it to me that the tray design was changed after a number of customers phoned up about the problem.
If it fails in the first 3 months they will replace it with out question. After that they will query how many discs you have printed on and it becomes a good will gesture on behalf of mangers and mentors. This is because as I have already mentioned it is a domestic printer not a dedicated disc printer. If you wish to go into the relm of printing hundreds of discs yuo will need to go into the relm of dedicated disc printers which are more expensive and are designed for such a purpose.
This is all legal under CPA.
The charge for the tray is actually Â£5 but Epson for cost purposes, and a number of shops do this including Tesco, Asda etc, have a minimum charge for orders and theirs is Â£10, so you can and sbould order 2 trays to make up the Â£10 cost. Therefore you have am extra tray for when the second tray wears out. Hopefully meaning your printer will die well before you use up the replacement trays, which is what the lady said to me.
Now you see I why said phone and not use the e-mail service. Because you can get the rep o speak to their manager while on the phone you can't force that with e-mail as they can fob you off.
