Hello
Fisrt off please hold down the 8+C buttons together, there will show a error code in the copy quantity display.
Now not knowing what the error code is, i am going to hope that it is C44 that is the most common
error code on the E163 machine. If it is C44 please do the following.
Switch off the machine.
While holding down 0+8 buttons, switch on the machine.
When ad shows on the display, input 400 then press the start button.
If the value is not 0, input 0 button and press the interupt and energy saver buttons to save the change.
Switch off the machine wait awhile and then switch the machine on again.
The problem should be sorted out.
If the error code is not C44 you will have to let us know what the error code is, by holding the8+0 buttons down together.

Here is hoping the machine is working
Regards

When this machine was started after connecting the Color Image Reader-E1/F1, the screen for the shutdown sequence appeared (and E732-9999 was recorded as an error history in service mode). When the main power switch was turned OFF/ON by following the instruction on the screen, the error code "E732-8888" was displayed. When connecting the Color Image Reader-E1/F1, follow the field remedy below.
- E732-9999 is recorded when a printer model detects a scanner for the first time. (This is not an error code but an alert.)
- E732-8888 can be displayed when a different scanner is connected to this machine.
1. Connect the Color Image Reader to this machine. (Do not connect the DDI cable).
2. Turn ON the main power switch.
3. Change the setting values of the following service mode items.
- Service mode > COPIER > Option > BODY > W/SCNR: from '0' to '1'.
- Service mode > COPIER > Option > BODY > SCANTYPE: from '1' to '0'.
Reference: For the Color Image Reader-E1/F1, this mode has to be set to '0'. On the other hand, it has to be set to '1' for the Duplex Color Image Reader-G1.
- Color Image Reader-E1: Platen cover model
- Duplex Color Image Reader-F1: Two-sided reversal reading type ADF model (DADF-M1)
- Duplex Color Image Reader-G1: Two-sided simultaneous reading type ADF model (DADF-T1: only for the iRC5180)
4. Turn OFF the main power switch, and connect the DDI cable.
5. Turn the main power switch ON.
Note: How to turn OFF the main power switch.
When turning off the main power switch, be sure to follow the steps below to protect the HDD inside this machine.

The H4 error is related to the Fuser Unit not reaching the correct operating temperature in the correct time. You can try clearing this error with the following:

Make sure that the machine is switched on and the error is displayed. Enter the Service Mode by pressing the following keys # * Clr *

Enter 14 and press Start. Then power off the machine, wait 30 seconds and then power back on. The error should have cleared. If not then you will need to call in a service engineer.

I do not recognize either of these codes (187 or 387) as part of the Aficio 2015 error list.

If the code is displayed on the screen, physically TURN OFF the copier with the main switch (red switch), wait 10 seconds and turn it back on. If it's an erroneous error, this should reset the error code. NOTE: THE ERROR CODE MUST BE DISPLAYED FOR THIS TO WORK.
