HP PSC2115 printer I have replaced the ink cartridge and now it keeps printing aligning pages and wont print normally. I have tried 2 different brands of new cartridge now

Important thing: HP inkjet printers having self align technology & its aligns automatically after replacing the ink cartridge/s.In the process of align it will prints align page &it will read it on the model.
Suppose if you replaced yellow cartridge, as usually it will print align page, but if one or more cartridges not printing properly align will not completes. Results every time it will prints the align page when its switching on. Align will completes only when all cartridges/print heads are in healthy condition.. Check the alignpage find out which colors are not printing properly, replace it to over come from this issue. Now you decide what to do?..

I just noticed in the link to your forum item that additional text appears that does not appear in the item itself. It looks like you are getting a message telling you to press Enter to align your print carriage. This is a common step after you replace an ink cartridge. According to HP.com, here's what you are supposed to do:

"A message will appear in the front panel display requesting that the ink cartridges be aligned. Press Enter to start the cartridge alignment. Two pages will print. Following the instructions printed on the second page, place the first page on the scanner glass in the lower-right corner and then press Enter to finish aligning the cartridges. Remove the page from the scanner glass when complete".

The link to those instructions is as follows:

Just follow the instructions I posted above in italics and you should be good to go. Good luck.

Using a photo print cartridge To use the photo print cartridge, remove the black print cartridge and insert the photo print cartridge in its place.
The photo print cartridge can be purchased separately and will optimize the quality of printed photos.
With the tri-color print cartridge and photo print cartridge installed, you have a six-ink system, which provides enhanced quality photos. For printing regular text documents, use the black print cartridge.
Use a print cartridge protector to keep either print cartridge secure when it is not being used. Figure 5: Storing the print cartridge

I just got off the HP help line.  After changing my black ink cartridge a test page was printing each time I turned the machine on.  This is very costly, in both time and ink as the cartridges themselves for this machine hold very little ink.  I tried to learn from HP tech how to turn off the test-print while keeping my color cartridge empty.  It turns out that you cant do it.  HP requires you to keep buying and using cartridges whether you need them or not.If you buy the color ink it will use it up in its testings.  And if you dont buy the color cartridge it will use up your black ink by printing the test each time you turn on the printer.  The printer was inexpensive sure, but I'm paying for it in wasted ink.

In the process of alignment there are two phases:

1. When the message comes to align the ink ..press ok and the page is printed out.

2. Once the page is printed then place the page on the scanner glass and tehn scan the same.

Follow these two steps in the same order and it will never give Align Ink Cart message again.
