Dear Sir I have an error with my HP Desighnjet T1100ps error 20.0:10

Tech Guys only:
Remove all cartridges, remove left side cover, disconnect IDS connectivity, take out IDS( Ink delivery system know as ISS). this unit contains two compartments left unit drives 0,1&2 cartridges and right unit drives 3,4&5 cartridges.. Remove both IDS driving motors, rotate manually & observe the driving shaft of the both units & find out which was hard. Each unit contains three individual compartments & fixed together. Some cases these compartments are lost their alignment while transport or usage results 20.X.XX error will appears. To shoot out this problem, adjust aliment carefully verify shaft smoothness & apply grease. Fix motors back check once again fix entire things.. It will solve you problem..
The reason behind error is if any one of the shaft having hard movement, motor crying to rotate the shaft result time mismatch between both units. Understand the issue.. think,, and do... best of luck..
