Printing jagged lines

[MDRP]

I have been using Hp 1510 for last 5 years in my home. ( i usually print max of 10-15 pages month) 

Now iam facing few problems with the printer.

It can print straight line properly. TEST PAGE  black and white  shown below

 I have tried many things to resolve the issue: such as 

Tried different software for printing, different paper, done everything on Hp diagnostics tool, update/reinstall drivers etc

So somebody tell me whats the problems with the printer ?

Welcome to HP support community.

Align the printer

1. Lift the scanner lid.

2. Place the alignment page with the print side down on the right-front corner of the scanner glass. See the engraved guide next to the scanner glass for help loading the alignment page.

   

3. Close the scanner lid.

4. Press the Start Copy Black button  or the Start Copy Color button  on the front panel of the printer. The printer aligns the ink cartridges.
