Hi @Harbansh,
Please try the following first:
1) Use genuine HP cartridges
2) Try and print lots of pages, so that printer can warm up and reduce the humidity in it.
3) Try using paper from a new sealed pack or from different box.
4) Try a known-good HP toner cartridge
Is the light print appears on the whole page or just in certain areas ?
