>> Status in HP Linux Imaging and Printing:
>>   In Progress

>> Bug description:
>>   2 problems :
>>   - first : For scanning n sheets, I need scan n+1 sheets. When I open
>> the .pdf created, the n+1 sheets is white.
>>   If I don't do that, for scanning n sheets, I get a .pdf whith n-1
>> sheets. The n page is white.
>>
>>   I don't understand what is the problem.
>>
>>   - second problem : when i want scan n sheets with the "unwinder" on
>>   the top of my printer e-all-in-onethe Hp officejet Pro 6830, I get a
>>   total .pdf white !
>>
>>   each time, I connect a data USB on the front of my printer e-all-in-
>>   one Hp officejet Pro 6830.
>>
>>   Please, could you some one can help me ?
>>
>>   In French / En français :
>>   J'ai acheté récemment fin janvier 2015, une imprimante e-all-in-one Hp
>> officejet Pro 6830. Je suis sous Linux Ubuntu.
>>   J'ai constaté 2 problèmes :
>>
>>   - Le premier, lorsque je souhaite scanné n pages en levant le capot de
>> l'imprimante, j'ai besoin de scanné n+1 pages, sinon je n'obtient jamais la
>> dernière page de mon tas de n pages à scanner. Pour ce faire, je scanne 2
>> fois la dernière page.
>>   J'obtiens ainsi un .pdf avec n+1 pages de mon tas de n pages, la
>> derniere page (n+1) est blanche. J'utilise par la suite un logiciel pour
>> retirer manuellement cette dernière page blanche qui ne m'intéresse pas.
>>
>>   - Le second : lorsque je souhaite scanner n pages avec le dérouleur en
>>   haut de l'imprimante, j'obtiens un .pdf de n pages blanches !
>>
>>   je précise qu'à chaque fois, je branche une clé USB sur la façade de
>>   mon imprimante. Je n'utilise donc pas mon réseau local et je doute que
>>   Linux soit en cause.
>>
>>   Pouvez-vous m'apporter une aide ?
