How to get the black darker

SOURCE: HP C5180 scanner won't scan an image

I'm running Windows Vista 64bit Ultimate Edition. Have the C5180, all-in-one. HP Solution Center continually closed, saying No HP Devices Found. I completely uninstalled the printer software, using the install utility. Then, using Add/Remove Programs, removed all of the other HP software on my PC. Then deleted the HP directory (in program files x86), and removed the HP registry key under software in both HKEY_LOCAL_MACHINE & HKEY_CURRENT_USER. Then rebooted. Once that was done and back up, I reran the install utility, but this time I followed the steps below (from here - http://hpanswers.blogspot.com/2007/12/no-hp-devices-detected-hp-solution.html):

Click on next until you get the below three options
(i) Recommended

(ii)Custom-------------->Select This

( iii)uninstall

Choose the custom install and click on next, ****

At begining of the installation, It gives you to 2 options

I) Yes, Check for updates..........

II) No, I prefer to do it Myself--Select this option and click on next

Immediatley in the next window ,you will have long list of softwares with the empty check boxes beside them.DO NOT select(check) Hp update, check rest of them and click on next to continue the installation.

You will able to open the HP solution centre with No errors.

Additionally, I did the following 2 steps, that I mostly found here (http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00897551&lc=en&dlc=en&cc=us&softwareitem=oj-54112-1&os=2093&product=1153481&rule=9653&lang=en)

Add the following files to the Trusted programs list:

*
hpqkygrp.exe , located in the C:\program files\HP\digital imaging\bin directory.
*
hpqscnvw.exe , located in the C:\program files\HP\digital imaging\bin directory.
*
hpqste08.exe , located in the C:\program files\HP\digital imaging\bin directory.
*
hpqtra08.exe , located in the C:\program files\HP\digital imaging\bin directory.
*
hpqthb08.exe , located in the C:\program files\HP\digital imaging\bin directory.


Open the following ports on the firewall utility by following the instructions provided by the manufacturer:

*
UDP ports: 161, 427 and 137
*
TCP ports: 9220, 9500 and 9290

Hey,
Your problem could be because of bad alignment. That means paper alignment and printer alignment don't match. There will be instructions in,your manual to properply align your printer. 
Hope this helps. 
Thanks

SOURCE: the black is printing dark redish brown

Dear friend, your Black Ink Cartridge is Empty thats why your printer is using the Colour Cartridge to produce the Black Colour. This is the reason you are having Dark Reddish Brown colour instead of Black.
