Neo2 Error Codes

...part 2

Codes: 1221 - 1226
These are PF (paper feed) issues.
In general, make sure paper wheel (on left with clean encoder disk) is free to move. With printer ON
make sure you see RED Led on (this is optical reader), make sure cables to encoder are in and
also interface (small board at rear of printer on right side next to Epson mother board) is also connected.
Check encoder wheel (clear disk with lines) for any ink/scratches. When printer turns ON place your
finger on the wheel shaft gently and make sure it tries to turn (it will just a little). If it does not move
then check motor connection to mother board. If this error happens during printing then it could
be a sticky PF shaft or loose belt - not too tight but not too loose either. Also make sure cable from
small green interface board to epson board is plugged in correctly. It can happen that during cleaning
etc cables can get moved out of their home position (slanted etc) so check all cables here

...part 3

Code: 131B

Head temperature sensor error. This "can be" over temp but often an intermittent connection.
CH71 pin 8 (pin 1 is bevel end of connector). Check the cable here for any bent or short pins/pads
from cable end - clean with alcohol and dry off. The voltage here should be below 3.3 Volts DC and
will change (up/down) as head heats/cools. If you read 3.3V dc then there is not connection to
mother board OR sensor bad (unlikely).


Code: 1400 - 1410

This is pressure pump timeout. It means system (ink) could not be pressurized in allotted time. Normall
it is caused by a cartridge(s) not being fully installed OR low ink. Remember the cartridges we use
are rather large (100% larger than epson ink ones) and so when low ink levels it takes longer to
pressurize and empty space. If all that is O.K, make sure pump is running - check connection if not.
Check pump hose is connected - no leaks, kinks etc. Check larger connector (6 wires) which is
pressure sensor is connected.

Code: 142D - pump life
Code: 1430 - ink pad life
Code: 1432 - ink selector (black inks in head)

Gotta love Epson - so buy a new one right ? ---- wrong!
So, run Adjustment wizard (you have right?) and reset these counters - boom no $$

....part 4

code: 1601

This is paper width sensor error. On Neo2 (3880) it is disabled by unplugging sensor cable on
underside of head area. However, we found that ink can wick into this area and onto the connector
wire which resulted in false reading (moisture from ink). So, better place is to remove cable
from top-side of head - under the cover area. As a side note, on non Neo printers, this sensor
may still be connected (although disabled on Epson menu screen) and can throw this error. I have found
that simple cleaning sensor area and making sure nothing is underneath head area when turning on
printer - i.e sensor "sees" nothing as head moves during initialization.

Code: 150C/1531

This is ASF wheel error. Inside the printer, right side rear there is a black wheel attached to a motor
that has an optical flag on it. This error can happen if the wheel/flag does not break/pass the sensor.
This can be because wheel has moved off motor mount - they are /pushed glued on. Also check
connections to interface (small green board) and connector on Epson board. During power up this
should spin a few times - if not check connections.
