“Like most enterprises, print production has come to a standstill. While equipment can ‘rest’, we cannot let it ‘rust’,” said, Upendra Rajadnya, territory manager for lifecycle operations at Heidelberg India.

There could be a need to maintain the machinery for purposes such as security, compliance as well as insurance implications. Rajadnya “These maintenance decisions normally would have been planned over a specific period of time, but now they have to be done within days because they are idle.”

Rajadnya has shared a step-by-step process (see box below) for maintaining critical parts of the press machinery during the period when it is not in operation. “These are tips which will make it easy for businesses to get presses up and running again when the situation returns to normal.”

CoronaVirus or Covid-19 has led to a nationwide lockdown, threatening life and economy. “Let us rise in unison to break and beat Covid-19. Kindly co-operate and support the lockdown, by not stepping out of your homes. And for those who are in essential services operation, please implement recommended safety measures in the offices and shop-floors, thereby ensuring that both you and your colleagues remain unaffected of the epidemic,” concluded Rajadnya.
