Bad Print on Ricoh MP2501

[printertnc]

Buonasera
Ho un problema con una MP2501.
Non sono un grande tecnico come voi, mi sto' facendo le ossa con queste stampanti, e purtroppo non ho frequentato nessun corso, ho a disposizioni i manuali della Ricoh quelli di servizio.
Veniamo al problema
Le stampe escono come da allegato.
Il foglio viene macchiato anche dietro purtroppo, non solo davanti
Ho provato con un altro gruppo pcu + tamburo + developer, ma il problema si presenta comunque.
Dove sbaglio?
Ho anche provato a reinizializzare developer ma il problema persiste
I rulli di presa carta sono puliti, come pure il registro-
Il laser non l'ho toccato
Sto' diventato matto, che problema ha?
Grazie di cuore a chi risponde

Good evening
I have a problem with an MP2501.
I'm not a great technician like you, I'm doing the bones with these printers, and unfortunately I have not attended any courses, I have the Ricoh's manuals available at the service.
We come to the problem
The prints come out as per attachment.
The sheet is also spotted behind
I tried with another pcu + drum + developer group, but the problem is still there.
Where am I wrong?
I also tried to reinitialize developer but the problem persists
The paper pickup rollers are clean, as well as the register
The laser did not touch it
I've become crazy, what's wrong?
Thank you very much for those who respond

Laser slit glass or upper fuser roller?

+1 FOR THE HOT ROLLER

Hello you have to clean with a damp cloth the hot roller to fix it as this is your fused unit

you replace the hot roller

Then
After cleaning the transfer roller again, everything is clean again,
is now perfect.
Thank you all.
I have another problem, that was even before, a strange squeak when printing that comes from above, I do not think the fuser, maybe the rollers? I tried to put them in hands did not make a snoop.
Well, I can also see it in the future, but every suggestion is well accepted.
Thank you really for all of you, forgive me, but I'm doing the bones with these ricohs.
See you soon
