Offset preprinted #80 gloss through digital

[Bookletmaker]

Hi,

I am running shells that were printed on an offset press through a digital laser Ricoh pro c5100s. Every time I start running the job the first 10 have no issues but after that the toner starts blotching (images attached).

Approx the first 10 come out fine:



and then this starts to happen:



Is this an issue with the temperature of the fuser?

Thanks!

Maybe to probably.
Test hypothesis by:
Confirm the 'paper' settings are correct ie 'coated, preprinted.'
Test with settings for 'lighter, coated, preprinted' paper.
If the results are better then probably.
Last item to consider - is the job AQ or UV coated or have an overabundance of spray powder?
Some/one of these could maybe lead to picking issues.
YMMV

Were shells printed with wax free inks?
Did printer know they were going to be later digital toner imprinted?

I would try adjusting the fuser temp, print speed, and paper weight settings.

I would guess they applied a coating that inst allowing the toner to adhere.
I don't know Ricoh, but on my Canon I'd probabaly tell it it's 100#T so it uses the secondary fuser for better fusing.

i'd turn the heat up

See if these can be printed with UV inks
No powder or heat issues

I have only seen this happen when there is a flood coat (aqueous). Any coating needs to be k/o so the digital image can be placed on the original substrate surface.
