Z2100 error 79:04 when loading paper

[ghas]

Hi,

i'm having problem with my Z2100 44in. When i try to load paper it gives me error 79:04. It starts to scan for paper skew (RGB lights) and then throws error 79:04.

What have i tried:

-Reseating connectors

-Reseating formatter, hdd and ram + new battery

-I have run diagnostics, all OK

-Tighten belt

-Lubricating & cleaning rail

-Cleaning encoder

Z2100 has newest firmware TR8-TR_12_00_00-1_mvl40-x86-opt_B.

I have try to load the paper without printheads and cartridges installed but without luck.

Thank you for your advices.

Your case, check the tension of the belt... not too lose or too tight.... clean encorder strip & silver metal rod, also

lubricate it. 

If you changed the belt lately & had that error, check what belt & pulley etc.

-------------------

Myself have the same error on my Z3200ps .  reversion B 44". as soon as the carriage box moves to the left & 79:04 came right up.

without paper loaded & all tests were pass perferctly. But accidentally one time it loaded paper without error & perform

printhead alignment. Then after I swapped out with new printhead & next boot up & said paper not loaded correctly,

remove paper. So I did...... error again.

So far, that printer is still collecting dusts........

I have checked that but i will do it again. I have changed belt 2 yers ago, and printer was printing ok before this issue.

Additional info: I'm using refillable cartridges with ARC chip, i have also tried OEM carts without luck.

pay close attention to the pulley, mine was broke in the center & when loading paper & caused problem.

I was over joyed to find out the problem. Then after I replaced the new pulley & sure it worked .....

then after a while error again. I changed with other carriage box & gave me more error with color sensor 

error & other errors. at the end I just gave it up.

I have removed left cover and dissasembled tensioner. Pulley is ok. Still got error... This is so frustrating...

I really can not figure it out what caused it. See my photo & clean the area, left of the carriage box.

One time I got an error message & could not print & it said clean ???     I forgot exactly.   After I cleaned it & it worked again.

( yes, it had like hairs , lightly clogged & affect  lens on carriage box ) .

try it.

I cleaned the sensor on carriage, loosen belt and cleaned drop detector sensor, still got error. 😞

I have also reinstalled latest firmware. Also, is there option to install previous firmware?

Today i have cleaned printhead contacts and performed EEROM reset, but the problem remains the same. Do you have any other suggestions?

Ok, i have managed to get the printer to work again. If anyone have the same problem, the solution for me was to disable IPv6 and reset IPv4 settings (Menu --> Connectivity).

I just hope the printer will work without this problem in the future.
