4.3 HP ePrint Enterprise for Good

4.3.1 Red screen problems

Depending on your Good server configuration, you may notice a red screen immediately following the first

installation, followed by the first log-in. In this occurs, the workaround is to stop the running application and

start it again. The application will then display the agree screen and should work properly from that moment

on (with no more freezes or red screen occurrences).

This usually occurs if the configuration in Good server prevents the freeze. To find and set the policy, use the

Good Control web console: Policy Sets: Security Policies: check the “Require User Passwords”.

4.3.2 Boot loop problems

In Android devices running Jelly Bean versions 4.1.1 or 4.1.2, the boot loop problem is often noticed when

connecting to certain wireless networks. Attempted connections to certain wireless networks causes a

system error in the Android device, which then reboots. As the device boots up, it attempts the same wireless

connection, causing the device to reboot again, and resulting in a ‘boot loop’.

This happens because there is an optional attribute that is not provided by some routers that the Android

system code is expecting. A lot of Android technical forum posts speculate that it has to do with route to the

internet, or lack thereof (i.e. Wireless Direct). In some way, this combines with a new wireless settings menu

option provided by Android. The setting reads “Avoid poor wireless connections” and is in the form of a

checkbox. The prescribed usage/benefit of this setting is to aid customers in avoiding networks with poor

signal or bandwidth that could hinder their experience.

To resolve this boot loop problem, use one of the following:

●

First option is to disable the “Avoid poor wireless connections” checkbox. However, some

manufactures do not display this option to the user. So during the reboots you can quickly get into the

wireless settings and either disable wireless, remove the current network configuration, or disable

“Avoid poor wireless connections” then the reboots should stop.

●

Second option is to have the user leave the range of the wireless network, or disable the wireless

network, if it is a router to which they have access to.

This allows the phone/tablet to fully boot. The user can then disable Avoid poor wireless connections.

A network can now be selected from the wireless list (if the network is out of range or disabled, it

should be at the bottom), and choose Forget, which removes the profile for that network. The device

will not attempt to connect to it.

This is not a problem with the routers, but with Google’s implementation of the spec. Disabling the Avoid

poor wireless connections setting is the ideal method for dealing with this issue. However, if user cannot

access the setting, the remaining options are few: obtain a new router, wait for an OS update, or get a new

device.

4.3.3 Resetting passcode

You may occasionally see a prompt to enter the password for credential storage, instead of being prompted

to set a pin or password. This often means the user has not entered a password, or does not remember the

password. Online research indicates this usually occurs for users attempting to set up wifi or VPN.

If this occurs, complete the following steps:

1. Cancel out of the Type the password for credential storage window.
