Garantieservice "Parts Only"

van de Parts Only garantieservice zal HP kosteloos vervangende onderdelen ter beschikking stellen.  
Voor de Parts Only garantieservice is vervanging door CSR-onderdelen verplicht. Als u HP verzoekt deze 

onderdelen voor u te vervangen, worden u voor deze service reiskosten en arbeidsloon in rekening 

gebracht. 

Reparo feito pelo cliente 

Os produtos da HP são projetados com muitas peças para reparo feito pelo cliente (CSR) de modo a 

minimizar o tempo de reparo e permitir maior flexibilidade na substituição de peças com defeito. Se, 

durante o período de diagnóstico, a HP (ou fornecedores/parceiros de serviço da HP) concluir que o 

reparo pode ser efetuado pelo uso de uma peça CSR, a peça de reposição será enviada diretamente ao 

cliente. Existem duas categorias de peças CSR: 

 

Obrigatória

 – Peças cujo reparo feito pelo cliente é obrigatório. Se desejar que a HP substitua 

essas peças, serão cobradas as despesas de transporte e mão-de-obra do serviço. 

 

Opcional

 – Peças cujo reparo feito pelo cliente é opcional. Essas peças também são projetadas 

para o reparo feito pelo cliente. No entanto, se desejar que a HP as substitua, pode haver ou não a 
cobrança de taxa adicional, dependendo do tipo de serviço de garantia destinado ao produto. 

OBSERVAÇÃO:

  Algumas peças da HP não são projetadas para o reparo feito pelo cliente. A fim de 

cumprir a garantia do cliente, a HP exige que um técnico autorizado substitua a peça. Essas peças estão 
identificadas com a marca "No" (Não), no catálogo de peças ilustrado. 
Conforme a disponibilidade e o local geográfico, as peças CSR serão enviadas no primeiro dia útil após 

o pedido. Onde as condições geográficas permitirem, a entrega no mesmo dia ou em quatro horas pode 

ser feita mediante uma taxa adicional. Se precisar de auxílio, entre em contato com o Centro de suporte 
técnico da HP para que um técnico o ajude por telefone. A HP especifica nos materiais fornecidos com a 

peça CSR de reposição se a peça com defeito deve ser devolvida à HP. Nos casos em que isso for 

necessário, é preciso enviar a peça com defeito à HP dentro do período determinado, normalmente 

cinco (5) dias úteis. A peça com defeito deve ser enviada com a documentação correspondente no 
material de transporte fornecido. Caso não o faça, a HP poderá cobrar a reposição. Para as peças de 

reparo feito pelo cliente, a HP paga todas as despesas de transporte e de devolução da peça e 

determina a transportadora/serviço postal a ser utilizado. 
Para obter mais informações sobre o programa de reparo feito pelo cliente da HP, entre em contato com 
o fornecedor de serviços local. Para o programa norte-americano,  visite o site da HP
