Carriage misalignment OfficeJet Pro 6830

[1NN]

After printing about 19'000 pages on our OfficeJet PRO 6830, it seems to have trouble keeping the carriage aligned: there will be jumps of up to 1-2 millimeters between one printed line and the next, especially noticeable when printing tables. Sometimes instead of printing straight lines, it will print curves. The problem consists even when printing in "best" print mode. 

Aligning printheads will not help. 

Cleaning printheads will not help (performed third level clean).

Cleaning page snudges will not help. 

There are no other maintenance tools in the printer driver package. 

Is there anything elsa that we can do? 

What is the expected life (pages printed) for this particular printer?

I'm posting this for anybody else who likes combining HP printers with Ikea furniture: 

The[edit] Ikea furniture the printer was sitting on, resonated with the printer's movement, depending on the exact position of the printer on the furniture. This caused the misalignment. 
The printer settled back to (almost) normal when placed on a stable surface.
